That is a good price on that crank. It will not work with the pistons you have. The better way to go is that crank,wiseco stroker pistons,no spacers,cool head with domes machined for the stroker. Then raise your port timing a little.
pistons@ trinity,twister crank shaft,racers edge and many other shops.If i was you I stear clear of vitos products,just my bad luck past. Good luck
