I am really thinking about going to TBI rather than a 4 barrel holley or TPI. I have been told that the TBI setup is alot easier to work with than a TPI but I would want a 4 barrel TPI to feed the 383. Do you all think that it is worth it?
Thanks

 

how much hp are you projecting out of this 383? the two barrel 670 tbi will support 350 hp easy if done right

i like tbi alot its like the high rpm potential, manifold selection, and tuning of a carb, but with none of the downfalls like low rpm/vacuum signal problems, hence better low end torque

 

I was looking at least 350 hp maybe over 400 hp just not real sure yet what kind of gas mileage could i expect with a 4 barrel TBI and 3.08 gears and 700r4. with 350 HP
Thanks

 

probably as good as its gonna get
i think the 670 will do it or the 700

 

U think those injectors that come with that Holley TB unit will be enough for a 383? I would think maybe 88lb injectors, flow matched.
