Sounds like the one I have, basically a truck replacement motor.

Low compression, crappy cam power to about 3500 rpms, and crappy heads.

Heads and cam have been changed out of mine and it hauls now.

Rated at 249 hp with open headers, 4 bbl.

I'm not positive on the casting #s though.

Yup, pretty weak. Not much better than the stock L69 that was in there.

But, it's a 350, so it has as much potential as any other 350, except that it has dished pistons, so the CR will always be sort of low.
