I got a b17 with a spun bearing in the 3rd cylinder and the crank is scored pretty bad ive been searching for a replacement but not sure which other honda crank would fit it as a stroker. Ive seen other ppl on other forums asking if b18 cranks will fit but no actuall answer was given. So if anyone on here can help me out with some advice it would be great lookin forward to getting this motor running again thanks.

 

It really depends on what block you are using. B16 and B17 block internals will swap into any B16 or B17 block (same block/deck height)
If you use any b18 crank, youll have to get creative to put it in the shorter B16/B17 block...
My advice would be to look for a B18/B20 bottom end and start from there. Damaged Honda cranks are generally pretty worthless since used prices are pretty reasonable.
