Our company president, Skip W. strongly recommends the universal 90 degree wires, as they will fit perfect. Those that were running a point system often used 7mm plug wires, and this is not sufficient to carry the high voltage produced by the HEI unit. It is recommended that you use 8mm or larger plug wires. See our other listings for many needed accessories.

This distributor will fit most all Chevy V-8 carburated engines with a four pin module. It will fit earlier model engines equipped with point style distributors. Fire wall clearance may be an issue on some early model cars, but we have found many to fit with good clearance.

This is the perfect upgrade for your classic Chevy, or just part of a tune-up. It would not be practical to re-install the original HEI back into your engine if you are overhauling it.

Here are a few problems you are most likely to encounter, when using an old distributor.

excessive end shaft play

bushing wear

weak coil, worn or cracked cap, and button

weak module

corrosion buildup

weakened advance springs

gear wear

If going from points to HEI this alone is a huge upgrade.

All of the above can greatly affect the performance of your engine.

These are just a few of the things that most old distributors have going on with them. For the low cost of a complete brand new one, it just makes little sense to used the original distributor. When we rebuild any early model Chevy engine, we insist the customer purchase a new distributor. You will notice a performance difference in your engine if you have any of the above issues with your old distributor. All of the old HEI's we see have excess end play in the shaft. I'm sure the coils on them are not at full voltage. This is much more than the oem model. All car makers have dramatically improved the ignition systems on cars and trucks. This is an indication of how important good ignition is to an engine.

I consider this the absolute best mod you can do to your engine.
