So I've been doing a lot of thinking and I might just bite the bullet and do a 408 build but I just had a few concerns but my main one; is can I just simply take a 360 block (obviously after being bored and shop prepped) and drop in a 408 rotating assembly? I know the basics to building but will the extra stroke require any grinding of the bottom of the piston bores? Because if that's the case I'd be willing just to do a nice 360 build but the 408 kit is internally balanced so I can use my 318 flex plate, stall, and harmonic balancer. So I was wondering if any of you know of a company that sells internally balanced stock stroke 360 cranks? Thanks for any help -kory
