That should be the number...but it seems awful big...It may help if you do what Denny said and post what cam this is.....and some other specs about the motor.This is the time to get it all figured of with no doubts!!!!
Theres alot of people on here with calculators and converters to help and they may not be familiar with that specific calculator/converter.

The cam I used had a number of 57 degrees and called for a static of 9.5 to 1 to 10.5 to 1 compression.I also used rhodes lifters which lowers this number further under 3000 rpms.
