Good information guys.
I know the 350 has more power for the most part. Being I've never operated/driven a vehicle with a 292, and it is period correct for my truck, I'm leaning towards getting one if I can find one. I do like that it's built for torque, and since that's my main goal, I think it should suit my needs in the truck just fine. If I can find one I will build it for max torque & efficiency and go from there.
If there's anything else you guys can share, please do. The more I know from seasoned veterans, the better.
