So im thinking about upgrading my fuel injecters.
buti dont know wat size i should put in it its a 305 and all i have is an exhaust on it.
help would be greatly apreceated.

 

TBI or TPI?

 

tbi

 

Holley makes a better TBI ( I think it has a bigger bore/more CFM) but you could just get the injectores from a 350 TBI. Long agoI sawTurbo City (do a search) that sold flow matched injectors. Don't go with 454. You will have too much fuel and would have to change the pump for the additional volum.

 

Dont upgrade the injectors... With only having exhaust on the car, all the injectors will do is make the car run rich and use tons more gas. Unless you put a nice cam in, some heads, and a bigger throttle body, and some other mods, you will NEVER starve the engine of fuel. People have the misconception that more fuel = more horsepower, but is NOT true.

 

ya i get the wat your saying jr mechanic im planning on port and polish really soon and headers also im thinking on the cam.
but i also dont want to make it like a race car lol you know im trying to say ppl
im keeping as a daily driver sense im 16 and all. but i just want a little more power.
