Just built a new engine for a street stock in Wissota land. Runs ok but doesn't seem to have the power of the old engine that had regular pistons. Won't even turn the same RPM on the same track. New cam was exactly the same, swapped the old heads on this new short block. Pistons are down in the hole the same as the old one, used the same head gasket #. Just doesn't have decent power, should have had more than last year..
Any ideas out there?
Thanks/
