Things the previous owner SAID it had:

427ci engine with a turbo 400 transmission. (454 crank in the stock 402 block)
4.11:1 posi rear end.
Ceramic coated exhaust.
Brand new brakes all around.

Turns out, some of those were lies.
As far as the engine, who knows...I sold it after driving the truck for two years without having any rumpity rumpity rump. It couldn’t pull a greasy sausage off a plate it was so gutless. Any higher than 4K rpm and it just flattened out completely.

The rear ended turned out to be a 3.08 open diff.

The exhaust...spray paint.

The brakes....well...have a look at the pictures.
