Nice Fikse's

I wonder if it would make more power with some reproduction Max Performance (aka: max wedge) exhaust manifolds?

That's awesome Andy! Glad you are to a point where you can enjoy it again!

I don't need any more power (or noise). I actually thought the cam would be a little mellower than it is but I don't think I want to pay thru the nose to get another cam ground. Using roller cam bearings in this engine wasn't my brightest idea. I should've just stayed with off the shelf parts so I could swap cams easily.

What happened to the 550hp 470? That seemed like a sweet combo for that car

That was a very good engine and maybe I should've kept it. But you only learn by trying new stuff. I sold the 470 (actually was a 466) to a Moparts member several years back. I then made the classic mistake of getting too fancy with my next engine. The low deck 512 has cross bolted mains, roller cam bearings, 440 size main journals, etc. It has a Callies crank, Crower rods, etc. Way, way overbuilt for what I need.

I will most likely pull the 512 out in the near future and sell it and build something much simpler for the car. I have a 426W block that I can use. It won't be "numbers matching" but it will be closer to original than a low deck block since the car was a factory 426W car.

I'm also going to put EFI on the car and then I think I'll call it good. Well, maybe get rid of the Doug Nash 5 speed since it is a really clunky transmission and buy something modern like a T56!
