Thanks Don, let us know what kind of numbers you see on the dyno. Is it a chassis dyno or engine dyno? I wanted to run my motor on the latter but would have to sacrifice a flywheel to bolt the dyno brake up to.
There's more than one way to build a Jimmy and while your plan differs from mine, the main thing is to get 'em on the road and drive 'em! The F298 cam didn't work for me but in a lighter vehicle with lower gearing, it might be just the ticket.
Also, my decision not to overbore was a little different as I started with a NOS shortblock, and just didn't want all that "meat" ending up on the machine shop floor.
