Stroking a 318 to a 390

On an update, the MSD box is actually good, but we’re running on an HEI right now. Comp 274Xe break in went perfectly after we got it to light off. I’ll post some video onto you tube so we can share it, but we can’t drive it until the exhaust gets done, we're too close town to town for all that and they're already watching, LOL! It’s way over the edge of “extreme truck engine', it would easily run 10's in a properly set up A body. These things rev stupid fast, it can hit the 6500 rpm rev limiter before you’ve even realized it’s went that high.
