im in greenfield nh, according to google im about 840' above sea level. at work right now, but i will take a look at that link when i get out. one of the things im considering is building the motor for use with the blower, but running it without one until i can afford one.... will 8:1 scr be a complete dog without that blower?

Let's see what pistons are available to match up with the available chambers, then decide what to do. Naturally aspirated at ~8.00:1 wouldn't necessarily be a dog, but it wouldn't be a world beater either. Ideally, you would want to run less cam to match up with the 8.00:1 static compression ratio running naturally aspirated, then change back to more cam with the blower. The bigger cam might be OK though, with the 3000 stall converter that i suggested.
