There is only 1 crossmember for the trucks, for different transmissions, you just move it.

using the stock crossmember just have to drill some new holes. The keyless portion of my keyless chuck drill broke so i need a new one before i can get that finished. I got my wiring hooked up and my fuse block and relay center installed. Battery cables and radiator hooked up. Also started messing around in HP tuners.

Be careful messing around. You can really screw something up with it.

Mainly just reading and looking at all of the functions this program has not really anything to do yet as i havent fired the motor yet.

Any one know what manifolds fit the 73-87's I have been reading for hours and cant seem to find anything on 73-87s just 62-72s
F-body? vette? trailblazer?

LS manifolds? I used the factory 6.0L manifolds. If you get the later ones they should fit also (truck ones)

header from summit part# SUM-G908 $153.93 they are shorty headers fit 99-04 truck requires slight mods to PASS side rail, u can either cut the rail, or what i am going to do is take the header have it cut right above the flange and add about 2 inches of pipe in so it will clear.

do these headers have egr provisions? I am having a problem finding ones that fit but ALSO have egr.....might just need some made up but then they wont have a CARB EO# to pass smog

so i got my manifolds to fit. I cut the egr port off the stock manifold and welded a patch panel onto it. Then i took the egr mounting base and made a flange and welded a pipe to it and that mounts just above where the stock egr mount was. Now i have clearance. Found that the rear of the manifold still rubs but i will notch the frame and clearance the manifold and i should be fine. Everything still fit under the stock heat sheild so it looks factory still but i have my clearance. Now on to the gas pedal and e-fans.

So i got it to fire tonight turns out my PCM connector was not tightened down all the way. I had been troubleshooting 3 different circuits for weeks and then i tightened the connector up and it fired right up. Well now it is on to the last few things i need to tighten up or bolt on and then take it for a drive. Started scanning with my HP tuners so i will be looking over the tune and seeing what i need to do from there.
