I am going to hook up the stock TPS to my carb and allow my existing computer control the trans.
I bought the headers from someone on another forum. He said they are a custom set from Schoenfeld and are made to be able to reach the rear spark plugs.

I am using a earlier TPS, the 86-91, works great, and the hand held tunes everything, also allow lock up and performance shifting at the flick of a button/switch if you like. Dont think the older 4L60 that was in it would have lived behind this motor, yours probably wont live behind the larger engine you have with a cam.
Do your headers look like mine?:

Awesome build you have going on there. My first attempt at LS swaps was a 6.0 earlier this year that I ripped out of an 03 3500 Express. Poerted 862s and a .629 lift Comp cam got me an 11.34 first pass in a 78 Malibu. Lot lighter than your truck but something tells me speed will come.

Well, keep us updated on that Trans, I think it will die fairly quickly if you drive like me.
What MPH? Did a 6.0 in a Malibu with heads I touched up, only flowed 270ish, stock 317s, did 7.3 with 3.42 gears. Think it hit 96 mph? Had the torqer v2 cam, th350 with a 3500 converter.

i dont know if you are going to do the tranny or you know someone that does but i would suggest giving the tranny a once over before you put it in and i would also upgrade to a beast sunshell
