Magnum Adventure

I had a similar experience with the 460 I bought and ended up completely rebuilding. I will say its nice when its done fresh and correct the first time.

It may not be as bad as it looks, get block and heads check out. Best case they are good and you can hone, re-ring, and just clean up the heads, worst case new heads, a bore, balance, and new pistons/rings. If the 360 in your car now is OK, just take your time and get it done when you can.
