Re: Project: LM7 5.3 Into my iroc

Im using the truck harness as well, but decided to do ac and heater core delete. I am also running most body control components on toggle switches. This could come out really bad or really good......

Anywho heres my update:

I have billet fuel rails, Ls2 intake, Ls2 cam installed with new chain.
New ls1 water pump, Ls6 valve springs installed, F-body oil pan.
I have a drive by wire 90mm throttle body my buddy gave me, I am trying to sale it though....so I can get drive by cable. If your interested sheldon, I can sale it to you for real cheap.

Re: Project: LM7 5.3 Into my iroc

Be prepared for the sketchiest thing you have ever seen in your life. Sketchy, like i said, sketchy counts in my books. Its my temporary tq. arm re-location until i get a spohn one.

Yes thats a file, its not finished any more as i found some flex in it when i mounted it so im going to weld some verticle support in it. Otherwise it fits well. I know, i was surprised too!

Re: Project: LM7 5.3 Into my iroc

Question: are you going to attach the fuel filler neck to the car in any way? I'm about to put mine on and don't know if it's needed.
----------
Also - curious how you're going to be running the exhaust. I'm keeping the 700r4 and will have the same tranny mount as you do (for now at least).

Re: Project: LM7 5.3 Into my iroc

I dont feel the filler neck really needs to be mounted, its pretty stiff in its pl ace, i dont think its doin anywhere.

As for the Y, its going to be running down just under the pan and under the crossmember untill i go T-56. Sucks, but oh well.
