Your tranny should work. Almost everything should work since the body is identical except for the frontend. I'm not sure how that would work, what you would have to mod. You'll have one crazy sleeper on your hands though

Do know about the bellhousing and hood though.

You will basically have to have the wiring harness off of a LS1 F-Car...... Computers/harness will not work together at all.....Bellhousing as stated about is different, and I believe that the tranny is a bit different....ie: internal clutch engagement fork.....not sure on that though......
Intake wise, you will have to run a setup other than the "lid" system that the LS1 F-Car uses...

Youll also have to change the gauges if i am not mistaking, different k-member, ls1 tranny, ls1 pcm, radiators might be different, think that is all. Id sell the ls1 and mod the hell out of the lt1.
