Thanks Joe. Hopefully they chime in. Guess I should have asked a few more questions before I got started on this project.

Remember, I'm not building a race motor but a truck motor. I just wanted the most cubes I could get and have it look just like an original 336 on the outside. I think for 9 1/2 to 1 compression, those Speed Pro pistons are fine. Especially since 99% of the time the truck will be between 5500 and 8500 feet elevation ( much less cylinder pressure ) As far as RPM's, it will never see more than 4500 and spend most of it's life between 2200 and 3200 RPM. Haven't checked it with a GPS yet but I think 3200 RPM is about 75MPH

Thanks for the input guys. Keep it coming. Hopefully I'm not painting myself into a corner.

Greg
