I want to build a 351W-based Ford Stroker motor. I've seen engine kits all the way up to 470 cubic inches (assuming a Dart or World Products 4-bolt block). But I also see many 408, 427, and 454 kits as well. My question is, what is the optimal bore to stroke ratio before the piston side loading is perhaps no longer ideal? 2 2008-11-03T00:30:42-05:00 38 78 521 0.869739197265617 active 2010-02-02T21:48:18-05:00 41 3149 0
