I drive a 1990 Corvette Coup L98 with the Z51 suspension package, I have been burning my own proms for it since about 2002, although I have not needed to do so in the last few years. [2.5 inch SS exhaust with Spintech mufflers, 1.6 RR arms, high energy ignition, air foil, relocated mat sensor, throttle body coolant bypass, adj fuel pressure regulator].
When the weather warms up Ill be installing an extrude honed intake manifold along with a set of AS&M large tube runners, a Comp Cams XFI camshaft complemented with a set Rhoads V-max lifters. While it is apart, i will also be replacing the dual mass flywheel with a Fidanza aluminum one. I have all the parts, I just need a warm garage.
