Clifford Performance has a lot of the inline 6 stuff. Also, you might want to check with Speedway motors. Years ago I bought an old front engine dragger with some other stuff. It had the 6 banger and a set of M&H cheater recaps. It had the funky OLDS rear and was built out of muffler pipe. I stripped it 'cause I didn't have a big enough set... :shock:
