Revving this thread with some updates.
Barn motor is installed. Tranny has been overhauled by jakes performance with one of his own 9.5 inch 3k stall lock up converter. Due to my lack of due diligence, the 6262 had to be sent to Bison for overhaul. Got it back but it still leaked oil so it's back at Bison's. Have a TA49 installed at the moment. Had some issues with the TR6 unit popping code 16 via the tachometer. Sent it to Bob and he couldn't find anything wrong it. My troubleshootin g revealed nothing wrong with GG, so off with the TR6 and back went on the stock ignition module and coil pack.
Went to the track last weekend for some shake down runs. Pleasantly pleased with everything except that I have a 49 on there instead of the 6262.
Ordered some 30 spline moser axles, eaton posi with bearings and a set of Mickey thompson pro bracket radial slicks in 28x9. Should be an anxious week of waiting for things to come in....
