Starting a pretty odd project that I need some advice on. (TBI to MPFI conversion)

[jdyates]

Hey, guys! Figure this would be the best place to ask a few questions about this project.

Here's what I'm working with so far:
-1995 Hummer H1 (yes, you read that right)
-TBI 350
-4L80E trans
-2.73 gears
-40" tires

This is gonna be along read, but I'd appreciate any input! :)

Alrighty, so me and a friend are starting a project for the H1. So far, we have intalled a Whipple on top of a Performer for a little more power, and installed a Walbro adjustable fuel pump with a 454 2" throttle body, with stock injectors, but now we wanna go bigger and badder, and have a basic plan.

My buddy, who owns the H1, picked up an Edelbrock 3502 intake (info HERE) and wants me to build the motor up a bit. So far it looks like we're gonna do:
-Aluminum heads
-Cam swap, I wanna go roller if it isn't already.

And obviously gonna need a tune for all this. (Already emailed Mark, waiting for a response.) We have the Edelbrock MPFI chip, but we need it tuned for the Whipple, and it is a different chip than the current computer uses.

Right now, I need to know what type of heads y'all recommend. Are there any nice aluminum heads around that offer good performance and fit the TBI intake bolt pattern?

What type of cam would y'all recommend?

Also, according to this chart:


I should be running at least 4.88's, so what gears do y'all recommend personally?

I appreciate any info y'all may have! We'd like to start as soon as possible! :)
