would like to swap TBI to Carburator. TIPs?

I have a 91 camaro rs 305 tbi and im tired of the vaccum and electronic BS. I want to swap to a carburetor. I guess to get rid of the vaccum i would have to change the manifold also (NOT SURE). Mind you I dont have the best budget and this will be a daily driver until next spring. Thanks

If you want to keep the factory fuel pump in the tank you can use the billet fuel pressure regulator from Jegs. It will hold 20 psi inlet pressure and works great.

Make a note, get a holley or holley type (demon, etc) carb. edelbrock carbs suck.

a decent option would be a nice Q-Jet if you can find a manifold for one (spread bore) That carb when tuned right will knock down nice MPG numbers with good throttle response
