T56 Magnum Conversion
I did get the shim, which I ordered from Ebay from Van's Auto. You will have to trim it some for the scattershield and the small block, but it fixed the problem with the starter rubbing. I took it around the block yesterday, most things seemed pretty good, so I washed all the dust/slag, etc off the car last night. Tonight I took it for a ride and I found that somehow I must have flipped the blocks inside of the pot coupler so the column has to come back out, and also no matter what the internet says, the transmission is 12 pulses/ rev on the VSS, not 17. I originally programmed it for 17 - and it was showing 37 mph when I was keeping up with traffic that was going 50ish. I already reprogrammed it to 12.
First impressions are...this thing really makes the car...and the car does better driving at low RPM than I originally expected. Runs fine at 1300 rpm in 6th. The transmission has way less gear noise than an A-833, so the car sounds significantly more refined.
