To me stock replacement means a part that directly fits/replaces an OE part and has the, or operates in the same perameters as the old one.

i'm not sure about the whole dist. but the dui coil looks and goes in the same place as the o.e. ones. so i would consider that stock replacement. i could take a dui coil and put it in a wells box and take it back to autozone and nobody would know the difference, b/c they are identical

My track rules said stock hei. they didn't like my accel dist. they want stock gm casting # on the housing. But the shaft and internals from the accel fit so i swapped the parts over to factory housing. thats one way around that rule. lol

this is a question that allows for considerable variance depending on whether the track owner or tech man likes you or not.
I mean a racing spring or shock that is identical to a factory unit in mounting and dimension is not in anyway a stock replacement unit. put one of each on the right front of a street car and try it. I would speculate that it means the repl part must duplicate the performance characteristics of the original part designed for that particular automobile as it was produced. this goes back to the old standard, "When in the Vatican, don't **** off the Pope!"

Light it up, Baby!

To me, stock replacement is replacing a worn out OEM part with a new stock part. No trick parts, even if they are stock appearing. My rules are pretty open, so its not cheating, but my distributor looks bone stock. However, it has an MSD module and a an aftermarket coil. That's not stock.

Just because it bolts into the stock location, that doesn't make it a "stock replacement".

Why race with 20 year old technology when something else may be better, yet still fits within the rules? Just like having to run 30 year old junk cylinder heads, it costs more in the long run.

stock replacement to me would be the mfg. part or rebuilt using mfg. parts and meet oe specs.

First of all what is wrong with 30 year old heads? Second if new is so much better why is there so many mid 70s cars on the race track?

True what you can get by with. At the track we been running they have a set of cast numbers we have to go by,so run what you can till you get caught,then run what they tell you.

This is out of our rules. The track says that this wording allows dummy converters, but not a full direct drive setup. I asked what car a hollow converter came off of but they just said it didn't say it couldn't be modified. Just depends on the officials I guess.

A) Stock passenger car automatic transmission only. All transmissions must have A factory stock torque converter. No valves in the automatics. Transmissions coolers are allowed but not in the drivers compartment.
