Aftermarket block street strokers.

So with the 400 block the 470 seems to be the street strokers with the wrist pins out of the ring lands and the extra support of the skirts. At least it seems that way for most, some always disagree. That's cool.

My question is with regards to the 4.5 bore aftermarket 440 blocks.

How much stroke can a builder get with the RB before the pistons get too short for the street considering the conditions mentioned above?
