    90 truck with 86-87 Corvette engine

    So I've come across another dilemma in my mind. I'm wondering if I could use the factory Corvette distributor that came with the motor instead of switching out with my 305 distributor. If I can wire it in and make it work I will. Or if it's best to go with my original dizzy then I'll do that...

    What is this high pitched sound coming from right side of the engine?

    I thought it was the AC Compressor but I removed it and bypassed it. I removed the belt and the sound went away. Could it be the power steering pump? It is not audible during low rps and only is heard in higher rpms. I don't always hear it always as well. The engine needs to heat up for me to...
