    Could be 3 things. The fuel pump, the fuel filter or the “sock” in the tank. You could just replace the pump, you’ll need a pressure gauge to test. It should push around 5-7 PSI. Replace the...

    The stock 401 journal is 2.248". When they cut the rod journal to 2.1", they remove the metal off center, taking as much as possible of the material from the bottom. This moves the center line of...

    Stroke is determined by the crank, not the rods. A 401 crank has a 3.68" stroke, the SBC 327 has a 3.25" stroke. The shorter stroke will rev higher and quicker. There's less piston acceleration,...

    Bigger isn't better, and a Jeep isn't a sports car. What do you use it for mostly? Mud bogs, drag racing, rock crawling? Different use means different builds for different power bands. You can't...

    The oil pump turns about 1/2 the RPM of the crank, so a simulated idle would be about 500 RPM at the pump. The pump, if it builds 50-60 cold PSI will nearly stall a 1/2" drill. I agree with trying...

    The cover isn't rebuildable. If the side clearances are above clearance specs, the only thing to do is replace the cover. Some scoring can be ignored if it isn't deep. Did you check end clearance...

    Very poor job on the part of the machine shop. Yes, all the rockers should have oil holes. Damn Chinese crap. I never put the valve covers on until I prime the oil pump and see oil at ALL of the...

    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...
