Steve, I just purchased several sets of Isky lifters [SB02] and push rods [SB03]
and the lifters are just as you describe, around 1/3 shorter. I bought them for
the chevy rod motor that I am putting together, and considered my self lucky to
have found them. When I talked to my machinist about it he promptly burst my
bubble by saying it is a waste of money. With thoughts of, yes so what's your
point, I bought the stuff anyway and intend to run it in the new motor. Do not
know about longevity or power gains but since you have a set that came with your
race car and the after market also made them I feel more comfortable about using
them. Jim
