is there a way to find out how much different they are Bruce? like maybe .050 or .060 ?
i should have addressed this when i had the motor apart but i assumed summits lifters were the right ones and didnt think to second guess their info
Smallblock seat height was 1.88 Big block was 1.91. Which still doesn't solve your dilemma, because it's less than the BB. Did you happen to notice any slop before you pulled it apart? I ask because you never know what someone did before, like shorter pushrods etc.
