I've been thinking of buying my friends 403. Will my tbi perform good on it or will I have to carb? Is the 403 any good? I plan on rebuilding it with all the forged goodies so I can run NO2 eventually. ------------------ late model 91 rs fully loaded t-tops red leather paint- gm red and yellow blend (light red) custom pink rims 305 tbi 14"x3" O.E, computer chip, accel super stock plug wires MTX sub and amp (very loud) vic_v8@yahoo.com

tbi will take computer chip burning learning and refinement. carb will just take a day or so to adjust. unless you are really into tbi and fully understand it, i would go carb if i were you. but tbi will perform just as well as carb, but it will take more time. advantages of tbi would be efficiency, ie, better milage, more precise air fuel ratio monitoring.

but for that you have to work for.
