going by the motor mount brackets and the accelerator pedal linkage, I'm going with V8.
That's my guess as well, but I figured if you had the full VIN you could confirm.
Not much left, but original disc brakes are worth $100 or so. The front sub frame another $100 or so.
I also see another sub frame, and a rear axle behind it. What's the code on the axle?
Is this a wrecking yard? The early model Corvair looks like it's a convertible, so there may be some parts on it the EM (Early Model) guys might be interested in.
