is it possible to put all the bottom end internals from a d16y8 into a d15b7? and which would have more power, d15b7 with y8 head swap, or d15b7 with y8 head swap and internals? i cant use the block from the y8 because it is cracked. any info would be appreciated thanks.

 

umm... you could save yourself a lot of trouble by picking up a new block. They're not that expensive.

As for wether its possible, I'm not sure :dunno:

 

true, but im trying to do this while spending the least amount of money as possible.
