DAVE's small-body HEI’s

Specializing in quality HEI, EFI Feedback HEI and 

MSD trigger pickup only conversions, hand-built 

into your stock points-type distributor


Now available - something different — true High-Energy-Ignition (HEI) that fits.

The objective is simple, build a dedicated General Motors type true High Energy Ignition (HEI), in either regular mechanical/vacuum advance curve style HEI, or, for Electronic Fuel Injection Feedback HEI (such as the Holley Commander 950 series, and other OEM and after market fuel injection systems). Or, a dedicated MSD magnetic pickup trigger-only system, into stock points distributors for American car engines.

My conversion ignition systems are designed around electronic components that are readily available from any good auto parts store. There are no special or unobtainable electronics or other parts used in any of my conversion ignition systems. The parts and electronic components I use are selected to give higher performance and spark voltage output than the so-called "drop-in" conversion and stock point type ignition systems now available.

My HEI conversion ignition systems are suitable for stock, mild to mid-level performance engines, muscle cars, street rods, hot rods and any application where the user wants a better ignition system. All my HEI systems run on full battery voltage. No ballast resistor is required.

The MSD magnetic pickup trigger only conversions are designed to allow MSD and other performance ignition units to be used on distributor applications not covered by available MSD trigger only distributors, and for those users who would prefer a stock distributor look instead of the aftermarket units offered. All my MSD trigger only conversions come with a dedicated MSD connector plug, and will connect directly to most aftermarket ignition boxes available today. Wire-up connection to the 6A, 6AL, Digital and BTM series ignition units is a simple plug-it-in operation.

My HEI and MSD Trigger conversions use stock design point type distributor rotors and caps. Therefore, the ignition coil is NOT mounted in the cap, and is always mounted remote from the distributor, as a stock point ignition coil is. I will not ever use a coil mounted in the cap, as these coils are always epoxy filled, not oil filled, and run hotter than oil filled coils. Epoxy filled coils are simply not reliable, and they do not produce consistent levels of spark output performance as they heat up.

I offer three distinctively different conversion types 

Traditional mechanical/vacuum advance type HEI, for carburetted engines. The traditional type HEI utilizes a stock design HEI module with 4 pins, functional mechanical and vacuum advance curving, and is suitable for non-electronic fuel injection applications.

EFI Feedback HEI for electronic fuel injected applications and aftermarket EFI conversions (mechanical and vacuum advance are locked out for this conversion), such as Holley Commander 950,  and other after market type systems. These conversions utilize an Original Equipment Manufacture General Motors 8 pin feedback HEI module, which allows the EFI computer to regulate spark advance. These conversions have the stock mechanical/vacuum advance locked out.

MSD trigger only, for use with MSD and other specialty ignition controllers. This conversion is a dedicated MSD trigger only system, which retains the stock distributor’s mechanical advance, and if so desired, the stock type vacuum advance as well.

All these conversions can be done to most stock OEM points distributors, and most aftermarket distributors such as MSD, Mallory, Accel and others.


HEI, EFI Feedback HEI and MSD trigger only conversions are available for the following distributors:

EFI Feedback distributor conversion pricing, for ALL distributors (includes the 8 pin HEI module and wire loom from distributor to module), (some distributors, such as Ford V8 will require a remote HEI module mounting. Others, such as most aluminum GM window types, can have the 8 pin module mounted on the underside of the distributor body, as the non-EFI feedback modules are), $195.00

AMC

Delco-Remy V-8 window-type distributors only. Prestolite distributors cannot be fitted with my systems. Delco-Remy units fit all V-8s.

Ford

All V-8 engines using 1958 thru 1974 point distributors

Y-block, using 1958 thru 1962 mechanical advance w/vacuum advance distributors (Load-A-Matic can only be converted to EFI feedback HEI use)

FE, 332/352/360/390/406/427/428

221/260/289/302 Windsor

5.0 conversion, for new crate engines, to use carburetor instead of EFI

351 Windsor

302/351 Cleveland, 351/400 Modified, 429/460 Lima (385 series), Boss 429

The Ford distributors listed above may be built using a small diameter cap and remote mounted (hidden) module for a historically correct look, or with the large-diameter Dura-Spark cap set and internally-mounted HEI module for a more compact, cleaner appearance.

General Motors

All V-8 distributors, window type only, 1957 thru 1974

All V-6, odd and even fire distributors, 1961 thru 1974

V-6, 4.3 litre only, conversion to use carburetor instead of EFI, built onto a modified V-8 distributor

Mopar

V-8, early Hemi, all engine displacements

I can build your stock cast iron distributor. Stock cast iron distributors can also be modified for 331/354/392 engines, fitted with a special collar for the main shaft with three different shaft lengths selectable from the collar, so one distributor fits all engines, no separate shaft for different length adapters. All Hemi distributors I build, HEI or MSD trigger only, can be built with or without vacuum advance, and all units come with a mechanical advance that is easily locked out for specific engine packages, such as with a blower and/or an EFI system.

Mallory

I-4, I-6, V-6 odd or even fire, V-8, point or Unilite, Comp 9000 point or Unilite distributors, magnetic type distributors.
Please call with your Mallory distributor type, as there are many different Mallory bodies.
Although certain smaller diameter distributors aren't convertible, most are.

MSD

Cast and billet design magnetic trigger distributors to HEI only (add HEI module).

MSD READY-TO-RUN

This conversion removes the unreliable and expensive MSD RtR module, converting the distributor to a remote mounted HEI module, new magnetic pickup and curving for your specific application.

PRO-COMP ELECTRONICS DISTRIBUTOR REMANUFACTURE

This remanufacture replaces the extremely problem prone Chinese electronics with quality United States made electronics, and adds two lubrication passages that increase lubrication.

MODIFY STOCK GM ZZ SERIES LARGE CAP HEI DISTRIBUTOR

This modification restricts the number of degrees used in the vacuum advance, for use with full manifold vacuum, and speeds the mechanical advance up to work correctly with the engine. This conversion also addresses the main shaft end play by shimming the end play correctly.


Custom Conversions

I have done MSD trigger and HEI conversions to Ferrari V-12, Auburn, Cord, Buick straight eight, 368 Mercury V-8, D-C Du-Coil distributors, the twin-cylinder cars at Disneyland, and the 1932 fiberglass project car built by Chuck Hansen and Joe Elmore on Horsepower TV, as well as numerous other distributors no one makes conversions for. If you have a special American car distributor you want to convert, please contact me and we can discuss it. Some can be converted, and some cannot because of the lack of available space inside the distributor for the magnetic pickup assembly I use.

When I convert your distributor, I completely rebuild it as a matter of course. I have to completely disassemble the distributor for cleaning and minor machine work to fit parts, so it makes sense to perform repairs and rebuild it at the same time as the conversion. During conversion, I replace both bushings, hard-chrome the main shaft for reduced wear, recondition all parts to be reused, and install new electronics, vacuum advance, cap and rotor. All distributors are curved to the engine and driveline application, and performance spark tested before return.

My Traditional HEI conversions carry a LIFETIME warranty on all parts and workmanship. The warranty does not start until the distributor is put into use in your engine.

This Web site is constantly under construction. As new photos become available of the conversions I do, I will add them. New pictures will be of actual customers' distributors, with the engine type. There are quite a few conversions I have not taken pictures of yet. I'm working on it.

Ford options:

Small cap with Dura-Spark terminals, add $20.00
This cap is designed to use the stock Dura-Spark 8mm wire sets while keeping the stock small diameter of the cap for clearance and/or appearance reasons. Works well with the MSD Trigger only conversions. This cap will fit all Ford V-8 distributors from 1958 thru 1981 that use clips to retain the cap)

Ford small cap is defined as the stock points design small diameter distributor cap and rotor

Ford small cap HEI conversions must use a remote mounted HEI module.

Ford large cap is defined as the three-part, clip retained cap-rotor-spacer stand of the 1976 thru 1981 Dura-Spark ignition systems. These cap sets flare out to a larger diameter as they rise above the distributor body, and have spark plug type wire terminals.

Point of information on Ford 1958 thru 1981 distributors: both large and small cap sets will install onto all V-8 Ford distributor bodies built within this time period. What makes one of my Ford conversions either a small or large cap distributor is simply the cap set I install on your particular conversion according to your requirements.

IGNITION COILS AND BRACKETS

NAPA IC12 performance coil (black) — $40.00

MSD 8200 Blaster II performance coil (chrome) — $50.00

Chevrolet intake manifold mount coil bracket (chrome) — $5.00

General Motors firewall mount coil bracket (chrome) — $5.00

The above coils and brackets are also available from your local speed shops and retail parts outlets, and are the exact same parts I would send to you. In most cases, you can purchase these items for less than I can actually purchase them for, so please, get the best deal you can on them. Don't feel you must buy the coils and brackets only from me for your conversion.

A note on EFI HEI coils. The EFI feedback HEI module is an 8 pin General Motors type module, and should have a stock General Motors type EFI coil used with it. Any good auto parts store can supply this coil, ask for a coil for a late model G.M. V8, such as 1986 thru 1992 Chevrolet V8. After market performance coils offer no performance gain from the stock replacement coils offered at your better auto parts stores.

RETURN SHIPPING CHARGE

A set fee of $15.00 is added into the price of each conversion for return shipping via Priority Mail (three-day service), and handling. EXAMPLE: A $195.00 conversion has the $15.00 fee already factored into the price.

PLEASE DO NOT SEND A DISTRIBUTOR IN TO BE CONVERTED WITHOUT A SPECIFICATION SHEET. WITH SOME FEW CONVERSIONS, I WILL NEED TO SEE THE DISTRIBUTOR FIRST, BUT ONLY AFTER WE HAVE SPOKEN OVER THE TELEPHONE, OR E/MAILED ABOUT SENDING THE DISTRIBUTOR IN FOR AN EVALUATION TO SEE IF A CONVERSION CAN BE DONE TO THAT PARTICULAR DISTRIBUTOR.

A word about payment for distributor conversions and parts 

At this time, there are only two payment options, cash and United States Postal Money Orders ONLY. NO OTHER FORM OF MONEY ORDER, CHEQUE (PERSONAL OR BUSINESS), BANK DRAFT, ETC., IS ACCEPTABLE. I find the United States Postal Money Orders to be a fast and reliable method of payment, and safe for both parties.

I require payment to accompany your distributor, prepaying for the conversion. The specification sheet has all pricing clearly listed next to the conversions/parts available. I only have ONE method of payment, UNITED STATES POST OFFICE MONEY ORDER ONLY, no exceptions. Payment specifics are outlined on the specification sheet. Distributors received without payment will be either sent back to the sender, or, set aside until the payment reaches me. I do not use the payment funds until the day the completed distributor is shipped back to you.

PLEASE NOTE, I ALONE ANSWER THE PHONE, DO E/MAIL RESPONSES, PERFORM ALL DESIGN, ENGINEERING, MACHINING AND MODIFICATION FUNCTIONS, AND PERSONALLY HAND BUILD/TEST EVERY DISTRIBUTOR. I AM ALSO THE SHIPPING AND RECEIVING DEPARTMENTS, CUSTOMER SERVICE, INFORMATION, AND HEAD FLACK TAKER WHEN SOMETHING GOES FULL ON WRONG. ALSO, WHEN YOU CALL ON THE TELEPHONE, PLEASE DON'T ASK OVER AND OVER IF DAVE IS HERE, I AM ALREADY ON THE OTHER END OF THE PHONE WITH YOU.

THANK YOU FOR YOUR INTEREST IN MY DISTRIBUTOR CONVERSIONS

HAVE A SPECIFICATION SHEET SENT TO YOU TO START YOUR CONVERSION

If you wish to have me do a conversion for you, and have access to e/mail, please e/mail me for a Specification Sheet to fill out and include with your distributor BEFORE you send it in. THIS IS THE FIRST STEP IN THE CONVERSION PROCESS. The specification sheet has important information for both of us, pricing, optional items, engine/drive train configurations, and simplifies the conversion process, plus saves time in getting the completed distributor conversion back to you. In your e/mail, please specify in the “Subject”, the conversion you wish, Regular HEI for carburetted engines, MSD Trigger only for carburetted engines, or, for EFI-HEI Fuel Injection System conversions. In the “body” of the e/mail, please identify the distributor you wish converted, examples, “1970 Chevrolet aluminum points small-big block”, or, “1973 Ford 351W”, etc. This way, I can send both the correct pictures package of a finished distributor and optional items, and a personalized specification sheet specifically for the conversion you want, which greatly helps the conversion process.

If you do not have internet-e/mail access, please call the shop for a paper copy, sent to you via snail mail.
