1) How did you arrive at that C/R? (No guestimates please)
2) What do you use this car for?
3) If you know what you use the car for then you also know what converter to get
A) If it's a race only car then you need an 7" or 8" converter W/ 5000 to 5500 RPM stall
B) If it's a S/S car then you need a 8" or 9" converter W/ 2500 to 3500 stall
C) If it's a street only car then you need a 10" converter W/ 2500 to 3000 stall

4) How do you plan on running 10.5 to 1 C/R on pump gas, when the limitation is 9.5?
5) It's not the static-compression ratio that's important it's the running or pumping pressure, which is determined by the timing events of the cam. On pump gas the limit for this is around 185 to 220 depending on how much ign-timing you run. We have found that 30 to 34 degrees of total timing works best on a S/S engine & pump-gas at about 175 to 195 psi with the cams we run.

6) There are several cams in the post for Brian any one of those will work for you, but in order for me to configure the cam correctly I need real info not guestimates!!!
