My thanks go out to Mike and ED at J & M Corvettes in Manchester CT for their help and, of course, for having their dynojet chassis dyno installed 8 months ago. If your in CT, you've got no excuse not to get your car dyno'd. Give 'em a call Check them out at J&M Corvettes...
This is the first run vs the best run. Between the first and last run we went down 5 sizes in jet from #78 to #73. The car was running way too rich and each time we brought down the jet we got more hp and torque. Adjusted the timing and changed the spring on the vaccum secondaries so they would open sooner. All in all I gained 42HP and 36ft/lbs. Not bad at all!!!
