I have a guy who has asked me to help him sort out a 90 Corvette with a ZZ4 crate engine installed in it. The car has the factory prom in it with an Edelbrock TPI high flow runners and a Holley throttle body. He has also installed an MSD box on it. The ecm is a 7727 with the factory speed density setup intact.
