Working on a 1991 Corvette. Installing new engine. GM 4bolt, zero decked, .050 head gasket, ETEC170 heads, Edelbrock high flow Vortec style base, ASM tubes, ported plenum, TPIS 52mm TB, ZZ4 cam, roller rockers, Carolina clutch conversion. Just replaced all the connectors in the engine bay and installing Thermo-Tek products over the tranny for heat shielding and noise suppression. Anyway having fun and getting anxious. Just got a Moates data logger to do some tuning when I get the motor installed.
