Plenty of room under the hood, its just that the chassis rails come together more just where the engine is, so the front suspension X member can bolt up. 6" further back the chassis, and no real problems. Our later 6.0lt exhaust manifolds may have fitted, but I couldnt get hold of any.
I am getting a complete C10 front end, and diff next week. It was part of the parts I sold with the truck when I sold it 11 years ago, and the bloke wants to have a cleanout, so am doing a trip to get it all, and some other bits.
Just thinking that I may end up fitting the C10 running gear into my truck instead of the heavier C20 gear. Any thoughts??
Wont really know until I get all the bits home, and have a good look at them.
Would love to fit an IRS out of a Commodore ute(Aussie El Camino), but big job.
