Slant 6 worth?

Not counting the engine, except as a "core". When was the last time you tried to by a Offie intake with carb, or a A833SO with a Hurst shifter? If I were in that area I would jump all over that for $500 (with hurst shifter), and I'm a cheapskate.
basically that sums it up right there.

it's an offy intake with a carb and maybe a shifter.

a crunchy OD box is basically scrap pricing, maybe you see some dimes on the flywheel and bell. the motor is core and a boat anchor and if you don't need it or know somebody that needs it you'll be sitting on it forever.

any of that, or if you tried to break the motor, you'll need a local buyer because shipping would put the kibosh on any deal.
