Chevy Tuned Port Injection on a 283

[Russ65C10]

Ok, I've been thinking about dropping chevy's tuned port injection on the 283 sitting in my 65. I've done a lot of reading up on it and I understand that while it maximizes the torque you get out of a 305 or 350 they tend to drop off big time past 5 grand. One of the things I love about my 283 is that it pulls strong clear to 6 grand, the down side is its a bit weak below 2500 - 3000. I currently have stock heads and reground RV cam. I am thinking of dropping on a set of Trickflow Super 23® 175, Aluminum, Assembled, 56cc Chamber heads with a CompCams 268 Fuel Injection friendly rollor cam.

So here is my question, do any of you have enough experience with Chevy's TPI to tell me if the 283 is small enough that the the TPI's runners won't choke it off over 5000 rpms or is it just the design of the TPI and the size of the engine makes no difference...

I currently am running a Edelbrock 1405 and performer intake, which with my RV cam and small valve heads gives me a engine weak below 3k and screamer above to 6k..
