You are my hero....

 

parish did this back in the day with a 6.0 and his 4.8l they both held up. but yes good numbers. can't wait to see the ls1 manifold numbers.

 

The intake is on, I just need a fan belt, and I have to hook up a few hoses. My wife and son are sick and I am haveing a hard time getting back in there to finish up. The Responsibilities start kicking in.

 

Well the truck is running! But not very good. I hooked everything up and my wideband is showing an extream lean condition. the injectors are not leaking, motor runs smooth untill I give it gas. It sound like a miss. I think I missed something. My vacume is normal! Is it possible to mix up the fuel lines, they both look the same?I have to look at it tomarrow. Wish me luck!

 

did you check all your wiring and your coil packs. i had the main coil pack harness disconnected once and the truck fired up idles ok but when i gave it gas it would respond so much lol. i would say check all your wiring first ro everything. do you have a way to check your fuel pressure also?

 

I think you are right! I think I may have something backwards. Fuel lines are right, I may have mix up the wireing. May be the injector conections. I am trying to find time to play with it. But the wife and kid are sick so I have to pitch in alot of time there. Thanks for the info.

 

good luck

 

Ok! It was a loose injector wire. I Think I lost quite a bit of low end torque, I just drove it around the block. Just alittle boost, it did not feel as stong. I hope as I drive it around alittle more it will get better. I hope it just feels slower but is much faster, like when the I first test drove the 93 camero (auto/lt1). I didn't think it felt fast but it was alot faster than my mustang (5speed,5.0,bolt on's and gears) at the time. That camero kicked my *** everytime, I didn't understand it, it didn't feal that fast. Anyway, I hope it gets better, or looks better on the dyno and track!

 

Have you done any tuning yet?? I would think your Ltrims are way off and Im sure your VE, PE, and timing tables would need some work. That intake is going to get air to the cylinders very differently than the ugly truck manifold. Get that thing tuned and on the dyno!! It would be very easy for me to swap manifolds while my engine is still on the stand!!
Did you use the truck rails and injectors? Did you cut the water pump neck and the alt bracket?

 

Like Greentahoe said, your air deliver could have changed dramatically so I wouldnt go mashing on it till you can datalog and ensure you are safe.
