I know the score with whats involved in fitting these pistons to silvertop zetecs, but do these also fit the blacktop rods. Only going to be a budget build as my dad just wants a reliable 240bhp. Dont want to chance skimming standard pistons.

Cant find anything on these fitting blacktop rods.

If the can be made to fit, how much would the comp ratio change being the blacktop rods are longer?

Cheers
