1972 Oldsmobile 442 W-30 Cutlass

The car is a real 442 - W-30 car, the 5th digit in the vin being a X clearly proves this. The car has a nom 455 engine that was fully rebuilt 1100 miles ago, and has a roller cam and work done to it engine vin on black shows 34M, M states it is a w 30 block from what I read?. It does have the factory G a heads that came on the W-30 motor, they have been worked a little, has headers but I have the stock exhaust manifolds to go with the car, along with the stock original air cleaner.. The car runs flawlessly and has around 510 horsepower. The trans is a m20 4 speed that also has no issues codes are 3271516wd and 3925661 show correct for 1972, no noises or whining noises. The rear is the factory 3.73 that was a option for that year. The car is super solid, little rust on the bottom of each fender and a pinky nail size on the drivers 1/4 panel.
