Thanks again Tag and Z28! Yes Z28, it's a 350 with TH350 and 10 bolt rear containing 3.55:1 gear. Originally it had 2.56:1 highway gear from hell which made it very hard to do this

I had Flowmaster 30 series installed, converting to dual exhast, after the engine was rebuilt. I replaced the front springs with Eibach which lowered about 3 inches. I had to cut one coil off to get the desired stance. Then I removed the original, rusted multi-leafs and upgraded with a pair from Classic Industries that lowered the rear 1.5". She sure does corner more aggressively now!!
I must say that moving from Colorado to the east coast has improved the engines performance. Much more oxygen at sea level than at 6,000 feet!

Anyone here ever do hole shots into their garage??
