hey guys I am using the corvette pulley, and the lower Idler pulley is hitting the sterring box. have anyone out there now of a cure for this? and also I was wondering i need to remove all the old tbi wiring, and if so what is the esiest way to pull it out whole. I have a harness that is labeled so i think i can stumble through that. Wiring is not my best part but I usual can figure it out. and des anyone have picks of the way you guys ran the heater core lines and the water pump on the lt1. thanks for all the help so fare. heres a pic of what i was talking about

did you replace the motor mounts? it seems to me like something isn't lined up right. every photo I've seen of a vette LT1 install has the idler pulley sitting well above the steering box.



it even looks like the pulley might be sitting behind the steering box a little, but its hard to tell because of the angle.

i used the factory ones, the only thing that I might have done is put the mounts on the wrong side. meaning the left on the right and the rt on the left. would that do it?

I dont think so. my guess is you have old mounts and they've sagged quite a bit. might want to replace them with poly mounts and I bet your problem is solved. can you tell how much interference there is?

the mounts arnet that old. I replaced them 3 yrs ago. and they lookrd really good. hummmmmmmmm

which clamshells, the part of the mount that bolts to the block, are you using?

the stock ones, im not sure what you are asking

heres another pic

Thats my setup above...I'll have to send you some newer pics from different angles Texas.
You have to reuse the original mounts from the 3rd gen V8.
I can't recall off the top of my head how close it is but I know there are no clearance issues anywhere at all using the 'Vette accesories. Something must be wrong like Texas said...you probably have the mounts in the wrong place on the block.

heres the mount to the frame:

there is only one place you can put them on right, its the same place i have put them on any onther v-8. right. or is there a diff place on the lt1 i didnt notice?

did i need to move the mounts up?

This is fuzzy but you get the idea:

hummmmmm wonder what is wrong?

Someone correct me if I'm wrong but I think there are two different places on the block that the mounts can attach. If you say yours is sitting on the mounts correctly, then you probably have them on right. they will only go on one way and actually 'meet' with the ones on the subframe.

one question, could I have the mounts reversed. I couldnt remember witch side was what so i went with even part#s on the right. or if they were wrong the engine wouldnt have lined up?

Trans Am, I'd definitely appreciate it. have you seen the new LT1 swap board I've set up? you can throw them up on there if you like. e-mail them to me at C07Robert.Reeves@usafa.edu and I can host them for you.


sean - I'm not real sure what to tell you man. if you put the mounts back in the forward position on the crossmember, the only think I can think of is you might have the block-side mounts on the rear holes. I know on mine the driver's side had to be moved forward when we pulled the 4th gen piece off. might check that.

well guys i got it to work. I replaced the mounts again and now i have the bare min clearance. it will work though. I would still like to see some better pics of the front of that engine. thanks again

does anyone know were i can get a ac delte pulley for the corvette pulley system? i will need to wait on the compressor seeing hoe it is diff then camaro.

I am trying to get pics for both of you guys. My car is 'away' for the winter but I am planning on getting over to it soon.
