Slammed68 Posted November 28, 2007 Share Posted November 28, 2007 Got the engine today, one thing I overlooked while thinking stuff through was the throttle body on the truck.. same as LS1? or do I need to scoop up one of those too.. The engine looked ok, dirty, but ok. There are 2 coil packs messed up, the circular tower part you plug the plug wire into, two of them have a peice chipped off of them, not sure If its going to be a concern.

Top Secret Posted November 30, 2007 Share Posted November 30, 2007 The throttle bodies on the trucks are mechanical while the LS1/6/2 are not. Please, read up a bit more on this stuff before you start throwing thousands of dollars around. Quote Link to comment Share on other sites More sharing options...
dlouis7 Posted November 30, 2007 Share Posted November 30, 2007 well i am doing the same swap and my throtle body was drive by wire. i have retained the drive by wire feature because i am using the original harness otherwise the throttle bodies are the same size. i know because i purchased a ls1 throttle body spacer and i fit perfectly.

Slammed68 Posted November 30, 2007 Author Share Posted November 30, 2007 I was planning on running a cable throttle. Dont tell me where Im throwin money. The trucks throttle body is a common upgrade on the LS1's, stock LS1 is 75mm and the trucks is 85mm. I think you need to "read up". Quote Link to comment Share on other sites More sharing options...
frank280zx Posted November 30, 2007 Share Posted November 30, 2007 Looks like a huge plenum will that fit a hood or is it the same as an ls1 plenum? So what are the differences in output for the truck and the car spec engine? diffrent comp ratios? cam specs? Quote Link to comment Share on other sites More sharing options...
Slammed68 Posted November 30, 2007 Author Share Posted November 30, 2007 Im using an LS1 intake. Already have the JTR headers, 05 GTO T56 tranny with B&M short shift, RAM lvl 3 clutch, fidanza flywheel, LQ4/LS1 intake tune, LS2 oil pan. Hoping for around 400 reliable horsepower with my setup. Ive done the research on the motor setup. These things can make awesome power for a VERY low price. Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted November 30, 2007 Share Posted November 30, 2007 Phew man, sounding sweet. Cracks in the plug area is not good. Should be a 10 minute fix at the pick and pull. I'm going to scavange a starter and MAP sensor off a truck this weekend. maybe snag the wiring harness just for spare wires and connectors.

Top Secret Posted December 8, 2007 Share Posted December 8, 2007 I was planning on running a cable throttle. Dont tell me where Im throwin money. The trucks throttle body is a common upgrade on the LS1's, stock LS1 is 75mm and the trucks is 85mm. I think you need to "read up". Wrong. The 85mm throttle bodies on the trucks are ELECTRONIC, not cable, which are the 80mm ones. Which is what you have. 6 months ago I was going down the same route as you, was going to drop in an LQ4 and T-56. I went for it because LQ4's are cheap, and make amazing power for very little money. They also offer good gas mileage. But I got out after I realized that all the extras were going to take a toll because I was going with a Gen 3 motor. A T-56 is hard to find for less than a thousand bucks, and the conversion to a carb'd 3rd gen is going to be at least another 600 bucks. Hard to do when your neighbor is selling a intake-to-pan 350 and a muncie 4 speed ready to go for a 1,000 bucks... Quote Link to comment Share on other sites More sharing options...
