Question for the experts.

OK, i have a couple of questions to ask. Ive been asking a few people but been getting different answers.

Would a Rb26 crank fit a Rb25 block?? If so i do i need to use Rb26 rod and pistons or can i use Rb26 rods and Rb25 Pistons?

Also whats the bore & stroke of the Rb25 & 26??

Would a Rb30 crank fit in a Rb25?

Thanks

RB26 crank rods and pistons drop straight into RB25 block, also get the oil pump as well if you can.

RB30 crank will not fit, RB30 block is MUCH taller than RB25 block.

Thanx war speed. Would Rb25 pistons fit the Rb26 Rods?

Yes but not with the 26 crank.
