    Glad you found it. I couldn't see if the PS pulley is factory AMC. There are 2 flavors of PS pulleys and pumps, 74 and older has a keyed shaft and pulley and has a nut on the shaft, 75-up is just...

    It could be that the PS pump bracket or even the body of the pump has been tweaked from over tightening the belt. I'd try installing a new pump and/or bracket to see if it fixes the problem. The...

    I know MC had the prints. I don't know if they were PDFs or anything like that. You might send a PM to jeepsr4ever here on the forum.

    I don't think the high mount alternator bracket is compatible with A/C. If it's the one I'm thinking of, the U shaped bracket goes on the 2 front manifold bolts behind where the A/C compressor is. ...

    I made one out of an old points distributor. Remove the distributor drive gear and slide out the shaft, cut the aluminum housing just above where the hold-down sits. Cut the shaft just below the...

    I have to say that I know Matt (owner of Bulltear). I do know that at one point nearly 50% of the covers he got were failing his check. I don't know if the manufacturer has improved their machining...

    All covers purchased from Bulltear are measured on a jig before being shipped to the customer. I am personally running 2 of them (one plain aluminum and one nickle plated), I haven't had any problem...

    Molnar is the only quality rod I know of. Their 2.100" journal has a Chevy wrist pin diameter, so you're looking at custom pistons with pin height adjusted to your stroke.

    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,...

    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...

    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...
