Thanks Bowsher.
Yep, its a 351W. Thermostat on the front of the intake, not on the block.
I'll likely part it out. Everything under the hood is new or rebuilt. I'll use the engine, alternator, volt regulator, starter, battery, aftermarket radio and that's about it.
Wish the 9" was narrower and it was a 4wd with solid front disc axle.
