Best fuel injection intake?

[scrub_the_k1500]

I put a simple Edelbrock Performer EPS and TBI adapter similar to this;

Chevy TBI Onto Holley Edelbrock 4 Barrel Intake Manifold Adapter 4 Bolt

1" Thick and CNC Machined From 6061 Aluminum Engineered To Install A 1.7" For Small Block and 2" For Big Block TBI Throttle Body To A 4 Barrel Intake Manifold Smooth Transition To Improve Air Flow Fits Both Square and Spread Bore Includes All Hardware and Gaskets For Installation Made In Grand...

I want to stay away from TBI, as stated. Never had good luck with the systems and I feel like power is left on the table. I'm running out of options though

Would be cool if someone would come up with an adapter to run ls style truck intake with rails and injectors right on top. Distributor would probably be in the way though.

That looks expensive, and too tall for my engine bay

Well...yeah. Holley made ONE of those, and raffled it off to some lucky bum.

Idle -6000. Really aiming for pulling power in the 1500-3000 range

I would absolutely build a crossram intake for it... ...I want to keep it simple and stock-ish looking

Welcome to the L31 Vortec engine. Cross-ram, multi-point injectors. OEM reliability. Stock-looking for '96-newer 5.7L. Power band pretty-much exactly where you want it.

The Treasure Yard will be your friend. Grab the entire engine with the accessory drive and accessories. MAYBE the transmission, and get the computer, and the wire harness. Expect some headaches that are solveable. Use a vehicle similar to yours for the donor--same transmission, same gear ratio, etc.

Or sell your truck, buy a '96-newer L31 truck.

the closest thing are these they are for vortec heads https://www.summitracing.com/parts/edl-7138 https://www.summitracing.com/parts/edl-71383 https://www.summitracing.com/parts/nal-12489371 if you do some searching there is most likely intakes like these for non vortec heads as well

You misstated your OP as 'stay TBI'. I got nothin'.

Edelbrock had a kit to swap out the TBI to electronic port injection just like vortec.

You must be registered for see images attach

Usually intakes are geared for either torque production, effeciency, etc., OR higher end hp production. Hard to find one that's good in both ends of the spectrum. Sometimes the best one for the job is the stock piece. Figure out what your main goal is.

I think this might be the answer I'm looking for!

My truck is a 98. It has the L31. So selling would be redundant. I'm not looking for advice on a swap. I already have that part down. Essentially I'm just replacing 350 engine guts with 400 guts and a bigger cam. If that makes more sense?

A 400 short block with a 350 top end.

Then stick with the factory Vortec injection. For the RPM range you are looking to run in, it works great.

0411 swap it and tune it.
