I have installed the crank and rods and pistons. Question: the pistons almost touch the counter weights on the crank. I mean on most pistons there is no clearance, It just does not look right. I bought this stroker kit thru summit, an they said this was normal. I have built many motors this is my first stroker. Any suggestions.
that's normal. You should have an EXTREME MINIMUM of 1/16 of an inch between the counterweights and the pistons. I generally prefer an 1/8 just to be safe.
