So after tearing apart my motor to find I bent all 12 exhaust valves and screwed up a rod, I've decided to replace to original beast. I found a J30A4 with 50K miles on it for $400. 90 day warranty, and delivered overnight from Tennessee. I recently replaced my clutch so I've dealt with the nightmare of dropping the front subframe. Any tips on making this swap any easier? I've up for suggestions. Thanks everyone.
