i have a bit of a delema. and i want to see what you guys think i should do. i have a 74 350 that has small valves and a new extreme energy 268 cam in it.i broke a valve spring and put the valve through the piston the lifters look brand new also i pulled them out and numbered them to there corresponding valves.in the meen time i piurchased a 87 350 with 76cc 194 valve heads that has just nbeen rebuilt.im going to use the cam in the new motor and put it in my camaro.the problem i have is do i buy a 2000 12" converter or use the stock one?is there that much difference between the two?when the old motor was in the car with the stock converter it seemed to be fine. but would the 2000 stall improve what i already have?its only a hundred dollar question...but why waste the money or will i?any body use this cam with a stock tc?
