383 Sbc Tbi ? (1 Viewer)

ok in my 60 buggy I have a 383 stroker ,,, currently running carb .,.. which TBI should I get and from where

Get something from a 5.7 (350).... unless you're running it at 6000+ RPM you'll never see a difference. There's more variance in flow of the injectors from the factory than there is difference in displacement from 350 to 383. ie. 350 to 383 is less than 10% increase in displacement, factory tolerance allow up to 10% difference and you're going to find something in a junkyard, so it might be even worse than 10%.

You could also get a TBI set up from a 7.2L and burn a chip to reflect the different flow rates.

Luke's idea is probably easier and is what I plan to do on my 383 F-100. You can also increase your pressure regulator to gain more flow.

I think the site is www.thirdgen.org for lots of mod info on the TBIs

interesting, factory TBI flow reported 470 cfm, no offense but what 6 cyl you running.

AIR FLOW, push fuel does no good without air.
