Re: Project Goldilocks, '66 C10 SWB BBW Build

John-
I had some reservations about the 6 right from the start. In order for you to achieve your horsepower and E.T. goals, it was going to have to be a pretty radical 6 cylinder. Radical can oftentimes mean temperamental, and that's no fun. I really like the idea of a LS engine. Those things make great power, don't leak, and get great mileage when coupled with the right components. Don't overlook the 4.8, you can find those engines CHEAP, oftentimes 1/3rd the cost of a 5.3.

I like the old straight 6 engines, but when you were wanting to go 13:1 on compression, I got worried. Even with good gas, a slight error on the tune can lead to severe death rattle (detonation) and that'll waste the rod bearings in a hurry.
