1966 Oldsmobile Cutlass Supreme Description

Up for auction is my 1966 Oldsmobile cutlass supreme, 4 door. I've owned this car for approx 3 years and done all the work myself.The engine is a 1970 455 bored 30 over with speed pro forged 2323 pistons. The stock crank and rods are 10 under with ARP rod bolts. Erson cam with .500 lift and 228 duration at 50. Roller tip crane rockers and new pushrods and lifters. Edelbrock performer intake with a quadrajet from a Buick 455. The distributor is the stock distributor from the original 330 engine. It has a pertronix unit in it, and was tuned by bubbas hot rod ignition. The headers are by hooker with a 2.5" summit h-pipe dual exhaust kit and flow master mufflers. I have the original steering box, but I replaced it with a box out of a Jeep Cherokee for a quicker ratio. Aluminum radiator with dual electric fans out of a 2003 Camaro.The transmission is a uni-case th350 out of a 76 6 cylinder nova. I replaced most of the bushings, new pump and tail shaft. The converter is stock unit but was rebuilt locally and is about 2200 stall. The clutches are alto tans and the direct clutch was machined to fit 5 clutch pack. It also has a dual feed modification done do it. When I bought the trans it was missing the kick down mechanism and I never installed it. I manually kick it down if I need too, but that big block usually doesn't need to be kicked down. The up shifts are firm if you have your foot in it, but the shifts are mild if you are just cruiseing around. It has a b&m cooler.
The rear is a 1971 8.5 gm 10 bolt with Eaton posi and 3.42 gears. It was sand blasted, cleaned inside and out and has new bearings all the way round. There are aluminum drums from a g-body Monte Carlo or Buick gran national. The rear lower arms are boxed and all the bushings are brand new moon bushings. There is a cutlass 7/8 sway bar on it, with about half a coil cut off the stock springs and new Kyb shocks. The front suspension has all new moon bushing, tru coil race springs and Afco spring adjusters and bilstein shocks and a trans am 1-1//8 sway bar. I've been driving the car all summer but it should have an alignment done.
I'm sure I left out a bunch of info, so if you have any questions let me knowThank you, happy biddingDan
