Aside from the 275hp limit it seems pretty good. 275hp is not shabby at all though.

How much would it cost you? Can you put bigger injectors in your current cfi, say from a 351 application? And what about GM TBI's I bet your could find a used one cheap for a 350 from the early 90's, if the bolt pattern is right.

bigger injectors wont work on a cfi and i dont think the oem gm's tbi would work gotta go universal holley

I've seen Holley MPFI systems that had a progressive quad throttle body setup. Pretty badass stuff.

I've installed this system on 2 different cars. It is NOT tuneable with a laptop. It has 5 adjustment knobs on the ECM and that is all.

The 4-barrel Holley Commander system is laptop adjustable.

Whats kind of response did you get from installing that type of TBI. How good did it work and how difficult was the hook up.. Also was it problem free or problematic? Was it installed on a CV GM TC?

[TommyN]

Why not just run a regular 4bbl carb and aluminum intake. Should make good power and be economical depending on the type of carb you get.

It wasn't on my cars. I worked at the shops that sold the systems. One was an ex-diesel ~81 Olds Cutlass with a ~69 Olds 350. Driveability was very good with the carb, so no big gains there. Performance improved slightly, MPG decreased slightly. The other was an ex-turbo 81 Trans Am with a 455. We put the EFI on it ~10 years ago and the car probably still isn't on the road.

Install wasn't tough. Drill a big hole in the firewall for the wiring, find a place to stick the ECM, mount an inline fuel pump, bolt on the system.
