So if I did that, should I get a 750cfm and a 600 cfm just to have for when I wanna go race it or something? And how much streetable power would I get with those changes?

In most cases, a small block chevy does not need a 750cfm unless you plan on using it as a drag car and you're making near 450+hp. The point of going with a larger carb is to give the motor more fuel at higher rpms. In your case, you won't be spending a lot of time in the higher rpms and 600 cfm carb will get you better torque response.

With the setup I suggested to you, matched up with your choice of heads, I would estimate that you would get between 383-400hp range, which is good cause a good engine build would get you 1hp for every cubic inch of motor.

Where can I improve things? Like is there anything else I can improve to make more power or get better mileage?

You really can't get both. Gotta try and find the balance between the two

Ok, I have been looking around on craigslist, and I found a TPI setup out of an '82-'92 camaro. I actually found 2. one with everything besides wiring and fuel injectors for $50. I also found a complete system with everything including ECU, wiring, and fuel pump for $350 and without the fuel pump for $300. Should I go that route?

Why am I the only one chiming on this topic? lol

Tune port injection is a decent "factory" setup but it is not meant for aftermarket built motors IMO. If I recall, I've read on several forums that the TPI setup falls flat on its face after 5500 rpm as it does not deliver enough fuel at higher rpms. It's a good start as far as streetability, but doesn't leave much room for upgrades as you will constantly need to get the ECM re-flashed to current specs or to meet upgrades.

If you go the fuel injection route, the best (and most inexpensive) is Comp Cams FAST system or the Powerjection III system.

See, thats what I am trying to stay away from. I need tos tay rather cheap. I am gong to look at a couple beefed F-Bodies Friday so I might get one of those to drive for now and piece together the 383 into a bada** motor making as much power as possible and not caring too much about mpg
