305? 350?
I have had my 91 Z28 for 3 years or so and have always assumed it has the factory 305 (5000cc). After pulling the engine, I see stamped on the back of the block top drivers side GM 5.7L.
So is this a 350? If so it explains a few things.....

Re: 305? 350?
Nope number there is completely different than VIN. Someone before me must have swapped motors.
It makes sense, the factory 305 tune was way too lean for this motor. I always figured it was because of the headers, but the displacement must have made a difference.
Anyway, if anyone in Oregon or nearby is looking for a 5.7 TPI, let me know. It runs good, I have a factory ECU EEPROM and a Megasquirt tune that I spent a bunch of time on...
