AThe manifolds are made from stock ones, contact Tom Langdon at Stovebolt Engine Co. I made the engine adapter from a piece of 3/8 in plate. It bolts to a chev bellhsg, the clutch is a centerforce that I had left from my 250in six and uses the internal hydraulic throwout with the T56. The flywheel came from Jerry Weigt. The pilot bearing and flywheel bolts are from a 5 cyl Colorado.

My question is does anyone have one of these runnig yet with a modified GM PCM ?
