So I just ran the class final at Indy.......

I would think if your if your Stocker had unaltered intake or exhaust runners that CC'ed less than spec., or combustion chambers that CC'ed larger than spec it's obvious you are not grinding and bead blasting or using acid on your heads. I would also think if your carb had the right unaltered part number on it and measured smaller than spec. It left the factory that way. With either scenario IMHO it's obvious no one is trying to cheat. Correct me if I'm wrong but you are not required to run the factory lift on the camshaft in Stock, you just can't exceed it. If a Super Stock cylinder head guru finds out by putting epoxy and brass in the right places and making the runners smaller the car gets faster. If they hold less CC volume that spec. will the head get tossed. Just curious, Don Jackson

The key as my brother wrote is there is a plus and minus number for the carb. Cam lift only plus would be bad. BP

Both are out. I think

Also if you are doing your homework you are going through a pile of cores to find the biggest that stays within specs, if being told it's too small you didn't do your homework.

"plus .005 or minus .015", and "max" or "min" size, CCs, CI, lift or whatever are 2 different specs.

Numbers can be counterfeited and parts can be machined/modified.

Billy, I'm surprised at you. Surely you know that the reason specs became so important is because people were mucking with "correct part number" parts.
