    Stock oil filter adapter? I would suspect the relief valve is stuck. Remove the large nut on the filter adapter (careful, it has a spring behind it). The plunger should move freely the full length...

    Only the AMC TF has the right bolt pattern for the engine. Chrysler TF has a different bell housing bolt pattern, same with a GM TH400. Since yours is a 71, the crankshaft on the engine won't accept...

    AMC changed from the Borg-Warner to Torqueflite in 1972. On the early crank (pre 72) the rear flange is perfectly flat, the later crank has a raised lip around the center hole. If your early crank...

    Can't help you much. I've kept the 360s I've built relatively stock, and most have been used in rock crawlers where torque is important, but HP isn't. The 390 in my AMX is at 10.1:1 compression. I...

    Unless you shave the tops of the 343 pistons, you'll end up somewhere around 11-12:1 compression. Way too much for pump gas and probably not great low end torque. A 390 or 401 will require notching...

    I believe they will, if you have a driver side manifold that dumps in the middle. The later Wagoneers (about 86-up) dump the driver side at the rear, you might still be able to use an earlier...

    It looks right. The only thing I'd worry about is if your machinist decks the block. If he does, then you're going to have to reduce the compression height of the piston by the same amount when you...
