| | | | Joined: Oct 2020 Posts: 2 Moderated | | Moderated Joined: Oct 2020 Posts: 2 | I'm pondering on rebuilding a 292 I have.
It will go in a ton Chevy square body.
Mated to a 4L80, in place of a diesel.
I have a good block.
Four barrel intake.
Will have dual cast iron headers.
This is torque build, not worried about gitty up and go ability.
Your input would be much appreciated.
I know the usual inline part sources.
Figuring on going .30 over, with high test pump gas compression pistons, and valve job and getting the crank turned.
I'd like a cam source, valve train input, piston sources, etc.
Vroom Vrooms and Boom Booms.

As far as the propane pistons mentioned above, when I did my rebuild earlier this year, those were scarce and not currently produced so prices when found were quite high, almost to the point of what new aftermarket high compression pistons were. | | |
