After reading all of the horror stories about the HO454 and HO502, has anyone had any issues with the ZZ502? Are they the same as the HO502 but with different cam ? I am asking about the carb version, not the Ram Jet.
Thanks.

We have seen bearing and ring issues on the zz502 as well...its hit and miss. If you buy one I would disassemble the engine and check all the clearances, rings, bearings etc.
