I have a 1994 LS.Head recently ported and polished and rebuilt with crower dual rate valve springs, titanium retainers and crower stage 2 cams, Skunk 2 racing intake manifold, DC Sports header, Greddy Cat Back exhaust, AEM Fuel Pressure Regulator, AEM Fuel Rail, Venom 30lb injectors, Upgraded 155 lph fuel pump, AEM Cold air intake, MSD SCI ignition and blaster coil with MSD distributor cap, 9mm plug wires and Iridium plugs, Flex A Lite fan and new radiator, AEM power pulleys, Apexi SAFC fuel computer.
What all will transfer over 2 a GSR motor?
