Back in '97 my red 70 GTO convertible was a show car. The trunk was painted body color and the battery and starter solenoid were moved back there. It looked neat. When cold, the starter spins like a banshee. When hot it barely turns over the 455 block. The battery and starter are both grounded directly to the frame, all starter cables (including the long run from the trunk to starter) are I believe 2-0 gauge (maybe 2 gauge?) - really thick with professionally applied terminals. The starter is an aftermarket high torque mini-starter with an asbestos type heat blanket. I have exhaust manifolds, not headers and they run close to the starter like a stock engine. The battery is new-ish and has a zillion CCA.
What else can I do to improve the embarassing hot sluggish starter problem (besides putting the battery back in front).
