This is very similar to what I did. My 383 is an original 2 bbl motor, so it has the low compression pistons. Because of this, I couldn't go crazy with the cam choice. I used 906 heads which were ported and gasket matched. Hardened seats were used. The head gaskets are Mopar .20" steel gaskets to help bring up a tad bit of compression. The camshaft used is a Comp Cams XE274H. Split profile .488/.491 lift. Holley DP 650 carb. I have a 700cfm DP carb, but for some reason my car runs like crap with it. I've had it back many times to the builder and it seems like my car just doesn't like it. Slap the 650 back on, and she'll run like a raped ape. Go figure. Rear end is 3.91 sure grip 4 speed. No power anything. I also have Hooker Competition headers which I bought directly from Jett Hot. (I strongly recommend Jett Hot if you're gonna run headers. Expensive, but worth it IMHO.)
If I had it to do over again, I would've waited and saved for higher compression pistons. Not that I'm totally unhappy currently, but I suppose I should've waited. That said, the car feels like it'll get to 100 mph in 5 seconds flat........
I bought my cam from Summit racing. I tend to use them, as they're one of the cheaper places around. They'll price match as well, which is a plus. And, I'm only 30 minutes away from the Ohio store, so that makes it easy. Not including the cam and header cost, total $ for my current set up was $1400. That was for the shop to do everything... Pull the motor, install new rear main seal, cam, etc..., head work, then put everything back in with headers.
Anyways, that's mine in a nutshell. Good luck with yours, and keep us posted!!
