Magnum Adventure
I'm pretty sure the 360 Crate Engines were built using seasoned (used) blocks and overbored .020. If the cylinder for that slug is bad, then it's another bore job. Mopar Performance does not recommend overboring more than .020 over stock but it's done everyday. I guess they're worried about cylinder wall distortion.

What does the cylinder wall look like?

Hey UOP, I just saw a picture of your RX7 in the March 2013 Hot Rod. One of the quickest 32 in the daily driver class at Drag Week. Threw them a curve with the Mopar Power. :finga:
