So here's a little history about why I decided to rebuild a perfectly good running motor. Bottom line, it had no balls! It's a 73' 400 block and 4X heads. 73's weren't the most powerful 400's built but this one felt like it had less than stock power. I posted on another forum that it was old and tiered and may need a rebuild and I was referred to Paul Carter here in Tucson. Some of you may know him, he's very active on PY. I talked to him about getting to 400hp and rebuilding the heads and he suggested going to a #16 head with more compression and that's what I decided to do as well as replace the cam. He asked me about what cam and pistons I had and of course I didn't know because I didn't build the motor. I had it in the back of my mind that this might end up being a complete rebuild because of the low power. Sure enough I pulled the heads and got my first look at probably the most dished piston on the market. I can't remember what the exact piston cc's calculated to but Paul calculated the engine compression at 6.7/1! Did I mention that it had no balls? So it came out and the planning began. And the clean up! There were 4 layers of paint and the last layer was painted on with a brush. It was a total mess. I did my best to strip everything down then took it to Paul for machining and some bead blasting and we started ordering parts. While I waiting for everything I cleaned up the engine bay, plug welded the holes in the wheel wells from the halogen breakers and relays, repainted the bay, and rebuilt the Quadrojet and power steering pump.
