You can use the throttle body, But I don't think you can use the injectors and fuel rails. I know the injectors have a different wiring harness plug than the car harness. I don't think the f/r will bolt up with the manifold because of hight differences in the bolt bosses. I could be wrong.

Yes and no. The truck injectors kinda fit if you remove the plastic base and use the car O rings. There's a write up on this in the LS truck forum with the LS6 intake. As pointed out, there are mods needed to hold down the rail. And I'm not sure the taller fuel crossover line would fit under a vette hood.

I used the corvette "batwing" pan. I am running short tube headers and side pipes. No issues what so ever. I had a lot of people tell me the corvette pan would interfere with the steering, but it cleared mine. Now I have a R/P so it doesn't matter.

i just got this flex plate by huges and stuff is that what you used?
here what they sent me
kinda dissaponted in this place they told me id get a belt with my under drive pulley and that did come, they said the flex plate and adapter was gonna be flat and the GM spacer which it isnt... i feel like returning everything and just using my stock flex with a spacer.

I dont have an auto but from I've read, use your original dished flexplate, buy the GM spacer with the part number given earlier, and the bolts.
Try SDparts for the spacer and bolts, you can search the GM part number there.

I think the holes you're referring to are the torque converter mounting holes. I've seen where they have been elongated to fit. Use the flexplate they sent you if that bolt pattern is correct.
But I've never seen that spacer and dont think I would mess with something other on here, or LS1tech have not worked with.
