I bought my '82 from a friend a couple of years ago. He bought it from his neighbor 2 years before that. His neighbor had a local Corvette dealer install a 'ZZ4' crate motor. It's pretty obvious this motor is not a ZZ4 motor. However it is a crate motor from somewhere, I'm just trying to figure where. I don't know if you've seen my previous youtube vids but after adding dual exhaust you can hear a slight lope in the cam.
This identifying mark says "1MMO330" and "7HO4". The engine is light blue in color.
Anyone have an idea of what these identification marks mean? OR what kind of crate motor this is?

Houston, sorry I can't help identify your engine, but I was wondering what induction system they used on it? Is it the original Crossfire EFI system that came on the '82?

YES, however I don't know what's done as far as possible injector upgrades, etc. probably nothing. I know one thing this thing as a lot of low end grunt, much more than you would expect from a factory 190 hp motor.
