Thread: 383 build with Rochester fuel injection

Tweet

I am in agreement that a 302 would be the way to go. Good luck with your project and let us know how it turns out.

if you do look for a roller 350 block---some are 2 bolt mains, some 4 bolt mains--and in the middle of that they went from 2 piece rear main seal to one piece seal---the one piece seal cranks take a different flywheel------

I'm going to buy a crate 350 and use my fuelie unit. If it doesn't work.....all I have to do is replace the intake with something else and throw the fuelie unit in the trash......

You could bolt a two-barrel onto a 400 and still get from point A to point B. Using an F.I. unit on a 383 may not be ideal from a horsepower standpoint, but the motor would still run and haul the vehicle around, wouldn't it?

With a carb, the air flow will choke in the venturi's keeping the mixture pretty well constant, right? The engine will simply "stall" at the point where it becomes air flow limited. Is it the same with the old mechanical injection unit, that the unit will reach a point of maximum air flow, and simply not add any more power beyond that point? Seems to make sense, but then I could be off base, too - just wondering?? I mean, it can't really lean out, as it will become air flow limited, right?

Project has been running for about a year. Went with a early 90's 350. Roller rockers, roller lifters, Duntov grind 30/30 style cam with 461 heads. Pulling 18" vacuum. There is never any hesitation, even on startup. This is all thanks to my FI expert in Scottsdale. Installed in a 1952 Chevy 5 window P/U. 3 spd on the column, Borg Warner fully syncro overdrive.

Very kind of you to come back around with an update. Thank you very much.
