Oakie,
You ever experience a chevy 292 inline six? Mine was pulled out of a 65 burb of the same body style as your truck. If you haven't already, check out
www.12bolt.comThe company helps guys build a mean inline six. Towing firewood and running a canoe laden 4wd to the waters edge, I like an inline six. I'm not brand loyal either, though the 292 is my favorite.
I have owned and run a ford 300 inline six.
In landcruisers: 12-ht (4.0 inline six turbo diesel) 2f inline 6, 3fe inline six, 1hdt turbo diesel inline six, 4.5L 1fz-fe.
In dodge: 6bt cummins. Chrysler slant six.
