A quick compare of the Predator 212 hemi versus non hemi harbor freight engine. Dyno HP and Torque numbers, parts availability, part compatibility, intake and exhaust differences.

I checked with a few people on horsepower, and flywheel regarding can you put a charging coil on the predator and there will be more results on that soon. Supposedly there is a kohler engine flywheel that can go onto the hemi crankshaft, but I have not been able to verify it as of yet.
