318/72 Dart build questions

Right now i have a 72 Dart with a 318 that is built fairly well and when it is running right it pulls really hard. My friend just got a '73 Camaro and is dropping a 454 in it to make into a street strip car. He is going to go with a big cam(not sure on specs), high rise intake manifold, headers, and some different carb(not sure on specs). I am not sure what it is going to be putting out but Im wondering what it would take for me to keep up with him.

My 318 has 10:1 compression pistons, 360 heads, big cam(kid I bought the car from didn't tell me anything about it), long tube headers, high rise intake manifold, and a 750cfm Carter AFB Competition Series carb. The transmission has been rebuilt with a shift kit and the rear end has a detroit locker and 4.88's in it.

I have read that it takes quite a bit to get a 318 to 450hp and if I were to pull my 318 I would rather start with a better platform. My dad has a 383 sitting in a 70 Coronet parts car that I could use and wondering if what it would take to get that up to spec with a 454.

One of the more extreme ideas I had that would allow me to not pull my 318 again was to do a rear mount twin turbo. That would cost a fair amount of money and take some time but I think the end result would be fairly cool. If I did it I would run 6-7psi and I have been told that the almost stock internals should be able to hold low boost like that. The thing I do have over my friends Camaro is weight, I think I will be around 3000lbs and he will be at around 3600lbsl.

Thanks for the help,

Lots of Nitrous Oxide.

So many variables here. Wait 'til he posts some numbers, then do your homework.
