Suggested EFI for a GM Crate LSX 454?

[PhillySpeedNYC]

I purchased one of these engines over the summer and have plans to use it in something soon.

GM does rate the power with a carb but the guys i spoke with at GM Performance didnt really have a suggested EFI kit.

I honestly want to run it with a Hilborn Style 8 stack but it has to be reliable for daily driving as i plan to drive this to work as much as i can

I am considering building a 65 Pontiac GTO using this powerplant matted to a Richmond gearbox.

suggestions on EFI shoot some replies as I am piecing together my parts bin now.

For driveability, FAST LSXr-102mm intake. Should tune real nice and flow well and make lots of power. Paint it, it aint the prettyest thing out there.

The Kinsler crossram is pure sex:

That bad boy is more than likely going to require a real good speed density tune to daily drive. Dont think I would do it for daily driving, just love looking at it

FWIW- Put a T56 or a tko600 behind that engine, sounds like a great project, I think the 65 goat was the nicest year, love it!!

If you're going to go with an 8 stack, which I think would be really cool, then the Accel Thruster or Gen 7 would be your best choice.

Those systems have more transient fueling tables than a FAST, Holley or other and you'll need that to make it run it's best, especially if it's going to be a daily driver. The Accel has fueling tables that will help it perform the way it should. When tuned right they (8 stack manifolds) make great power, I've done a few.

Shoot me a PM on what you think i would need, are you a dealer for these parts?

Pm'd you.

I'm abit more biased to Holley's EFI lineup regardless of which manifold you choose. I know Supremeefi is definatly the guy to goto if Accel was your choice, however it's the last system I'd personally recommend.

I tuned a few successfully, they're just not up to date and alot more cumbersome. Even with all the added tables, I'm able to get just as good results with "less tables" having faster processing, more resolution and more advanced backround algorithms.
