Ok, not to hijack a thread, but this quick run down of 4 gear racing: First, your set up was not meant to side step, period. 2nd, Keeping the rpms up by riding the clutch a second allows you to control the "stall" - like a 8" converter, keeping max power. Pop a clutch to snap parts and pull rpms down making less power is not how to race it. Friend at work did the same side step with his muncie Nova with slicks, breaking 12 bolt rears but never learned. Sorry, but I can't blame the 8.75 in your case.
