Yeah that setup should be around 11.7:1 compression. I've never been too impressed with Brian Crower cams and there a re better options than Toda B's these days. The Toda B's were kinda rough on timing belts too due to the ramp rates. I'd look into some skunk2 stage 2's or Endyn cams which are basically Jun3 copies for that setup. If you are having someone put your motor togther that really knows how to check valve to valve, valve to piston, and retainer to guide seal clearances then look into the Skunk2 Pro1 cams.
