MSD Ignition
El Paso, TX
915/855-7123
http://www.msdignition.com

rather than rebuild your old and probably well worn Chevy distributor you might want to look into upgrading to a new ball bearing shaft distributor with modern electronics and a matched ignition., theres also the option of selecting a small diam. cap & external coil version as it provides more physical clearance for some intake designs like EFI, tunnel ram and cross ram intake designs

PROVIDED its not defective if your buying it used?

the reason I point that out is theres a few total slimeballs that sell burnt out components at swap meets, so your almost always better off buying ignition components that are NEW rather than used.
the MSD 6AL ignition
is just fine for most street/strip application when matched with the correct components

this was a great choice in the 1960s but technology has made it rather obsolete

just like in every other component you select for an engine build youll need too shop carefully, theres a wide range in both quality and price .
some of the older chevy factory distributors can be refurbished to be excellent choices, and some of the newer after market distributors are cheap junk, so do some research, look for features that are important to you like roller bearings or replaceable bushings, and readily available replacement parts and tech support. I,d also suggest you look carefully at the distributor body and cap diam.... as many applications like with injection,dual quads, tunnel rams, etc. can make the selection of a small diam. or even a distributor-less ignition mandatory

keep in mind youll need a small base distributor to clear a holley stealth ram based intake, or several other similar aftermarket intakes that won,t allow the large cap hei distributor to fit and function

YOULL NEED THIS ADAPTER FOR SOME

your current distributor can usually be easily modified by a local machine shop with a lathe for an adjustable slip collar by carefully machining off the current one and adding a slip collar, if you need to make distributor gear to cam gear engagement or oil pump drive shaft length changes

heres the small base computer controlled distributor I selected for use with my custom ported and fabricated EFI intake
http://www.summitracing.com/parts/HLY-890-160/

this ACCEL DISTRIBUTOR looks similar, but check with accel for compatibility
I would not be a bit surprised to find out that accel previously built the HOLLEY distributors and relabeled them for HOLLEY

Holley's performance billet distributors are built with premium components to deliver consistent and reliable ignition performance under the most extreme racing conditions. The distributors are capable of performing to whatever rpm levels an engine is designed to achieve. They feature 8 degree vacuum advance and 28 degree mechanical advance settings, with 32 degrees of total advance, a magnetic pick-up, output wires for connecting to the magnetic input of most aftermarket CD ignitions, and caps and rotors that utilize brass inserts for improved electrical conductivity. Their stout billet aluminum housings work in conjunction with centerless-ground, case-hardened 0.500 in. shafts for increased durability. Caged needle bearings at the top and bottom of the housing create longevity and reliable operation up to 12,000 rpm.

looking for a bit more info or a dyno result?

http://www.eecis.udel.edu/~davis/z28/winter01/dyno/dyno031229/webpage031229.html

sure heres ONE, but its a bit deceptive, a decent single plane intake with the correct throttle body and injectors can EASILY support 500 hp in a 383 sbc when matched to decent heads and cam ETC.


heres the intake I used with 36 lb injectors, a crane 119651 roller cam and extensively ported 195cc trickflow heads on my vette.

Got it up and running in no time. The small cap really cleans up one of the most crowded spots on the C4.
the TPI F-body distributors will drop in a early c4

You need a small cap to HEI harness adapter and a pigtail/ plug for the coil wires unless you make something from junkyard parts


Image

Still need to mount the external coil, which I'll be doing off the wiper motor bolt with a bent L-bracket. Then I just need to tighten up the loose wires.

I absolutely hate wiring, so using the harnesses from EFI Connection made this a stress-less job. Only had two wires to slice, the Tach and Battery which go into the pigtail that connects to the coil.

The distributor came with cam lube for the lower gear, and the coil comes with basic mounting hardware. The harnesses come in wire loom and decent length for varying mounting locations.

* MSD-8366 Distributor

btw this is a rather cool custom touch, (VIDEO LINK BELOW ) you can swap to an HEI cap with wire routing that doesn,t look like crap

The new Powerfire Ignition System represents the latest state-of-the-art technology in ignitions. Look at this list of terrific features coupled with a price that can’t be matched for any other top of the line ready-to-run ignition system:

• Easy 3-wire install with no external spark box necessary.
• Precision CNC machining and hand assembled construction.
• Patent pending positive lock manual advance/retard knob. Distributor can be accurately advanced or retarded in 1/2-degree increments on the fly by turning the external adjustment knob. Each click of the knob provides a 1/2-degree change to total ignition timing. This makes getting an accurate setting extremely easy.
• Accurate super hot spark all the way through 10,000 RPM.
• Hardened steel .50” diameter steel shaft with sealed roller bearing upper support and bronze bushed lower support for extreme stability at maximum rpm.
• Powerful magnetic pickup and CNC machined reluctor pickup.
• Fully adjustable advance mechanism with easy to use spring and bushing design for a nearly infinite advance curve.
• POWERFIRE module built in for drop-in reliability from 50 to 10,000 RPM.
• Hot cranking spark as low as 50 RPM.
• Black anodized base with laser etched timing marks for easy visibility.
• High quality injection molded caps with brass terminals for long life and conductivity.
