I'm looking to have a 351W built for my 66 Mustang. Plan is it will be mostly street/some strip use. Looking for 400+ HP with maybe a small shot of N2O on top of that. The top end will be AFR heads w/ a custom cam. But, for the shortblock, I'm wondering if there are any "must do" items as part of the build. Weak links? Double roller timing chain, forged pistons, etc? TIA
