Wow, thanks... I guess I am asking for opinions from people that might have more experience in this than I do. Not sure what a forum is for if not that. After I do this I will be glad share my experience with people. But at this point I have never built a 390 stroker 11:1 motor.
For the CR, there are not a lot of choices out there for pistons. So right off the bat I was thinking that 11:1 was too high for what I was building. But it is right on the cusp of ok at 7000 ft of elevation with AL Heads. I can build a 9.6 CR motor with cast iron heads and call it good, but wasn't sure I was selling the motor short at that point.
