It's about 10 degrees smaller than I would run (I've built A BUNCH of them) but it'll still be very stout. I'd prefer a single plane TM7 but the RPM is still a good piece, you're going to have a ton of torque from about 3200-up, it will be fun for sure. There was a guy in Mopar Muscle with a Tan 70 RR that ran a combo very similar to yours (except auotmatic), he won the 6-8 car street shoot-out, so don't worry too much about missing the combo by much. Something that will help you out much more than a +10degrees @ .050 cam swap at this point would be to cut off the 3" collectors and weld-on a pair of 3 1/2" collectors to replace your 3" on the Hooker 5903's. You're torque and power peaks will otherwise be limited by the 3" collector which is the achilles heel of what are pretty well-built headers. At 511 cubes, that alone will be worth 3 tenths or more vs maybe the tenth you might see from the cam and the stock 5903's. Here's how it's done:

Thats a very similar grind to what I have in my 493 and my car flat out flys. The torque is awesome. I do have differents heads and headers (ported eddys, and 2" TTI), but still you should be fine.

How good where your rear tires for hooking Your going to need some goods one now with the 512 I would put the motor together and try it, the four speed can be made to make up for a lot of mistakes, which I don't thank you made on the cam. I would put it in and try it, be ready to shift it quickly or let off of the throttle if it starts to go sideways in first or second gear No kidding Let us know what you decide and how it works out Stroker motors make a lot of torque and torque is King Especially in a heavy car

The heads are unported. I may just do a clean up and port match after all is said and done. But it sounds like a good port job would be worth it.
Considering the actual numbers that have been posted , it would not hurt .
