I wouldn't bore a 340 block to run that crank/piston combo, wait until you can get the crank you really want. Instead, maybe do some home porting or something else to up the hp.

i was going to stroke my 340 this winter but funds won't allow it. a buddy is trying to convince me in machineing down a cast 360 crank and buy some new pistons to make 370ish cubes.
