    Adjustable Proportioning Valve?

    Any good reason to use an adjustable proportioning valve on my 70 Mach with front disc and rear drums? Should I stay with the stock distribution block until down the road when I will upgrade to rear disc. How does the adjustable work anyway? It has one entering port and one exiting port...

    70 Mach1 Rear Sway Bar Diameter?

    If I already have a 1" front sway bar, should I go with the original 5/8" that came from the car or should I go with the 7/8". I can only get a 7/8" aftermarket rear sway bar that uses the original mounting plates. All other aftermarket sizes mount on the leaf spring which I do not care for...

    Rear Sway Bar Problems?

    The PST kit comes with U-Bolts (more square) that wraps around the bottom of the leaf spring where it attaches to the axle housing. It then has a plate with nuts to hold it firm to the leaf spring perch. This is where the end link is bolted to the spring. Then the top of the end link attaches...

    Rear Sway Bar Problems?

    Why do the aftermarket PST and Mustangs Unlimited rear 3/4" sway bars mount on the center of the leaf spring? Why don't they use the stock mounting plate for the end links? My 3/4" rear sway bar from PST hits my sump for my gas tank. What's the deal? Anyone have the same problem?

    Torque Plate Hone?

    Is it worth for me to go back and torque plate hone my block. It has just been bored .030 over? I had my head up my #ss and didn't request for it to be done. The guy wants $150 to go back. I think the reason why it cost more is because he will have to hone the entire .010 to end up at .040...

    POR-15 vs Eastwood's version?

    I used Eastwoods Rust Encapsulator and Chassis Black for my '70 Mach restoration and it worked and looks great. A while back, one of the Mustang magazines did a test on which was the best against salt and humidity which causes the majority of rust problems. They took sample of metals with the...

    Boring With A Torque Plate?

    How much HP can you pick up on a 351w if you use a torque plate when boring? What are the benefits? Is it worth $150 to go back in a .030 bored block and use the torque plate and go to .040? How much HP am I paying for?

    351w Power Potential?

    When you guys say to use the Comp Cams 280H, is that for a '69 351w engine? Comp Cams has the retro-fit camshafts for engines that did not come as a roller from the factory. Do I need one of these retro-fits? What parts will I need for the roller conversion? After I do the roller conversion...

    351w Power Potential?

    What would be your approach if you were to build a 425 + HP standard stroke 351w? Of course money is always an issue but I am willing to do what it takes. Please remeber that the car will be for the street, so I really don't need a high rev (RPM) engine. Thanks for the help.

    351w Power Potential?

    Is it possible to make 425 or more HP from a stock '69 351w without stroking it? If so, what combination of parts would you guys use? The car will be used on the street so low end torque will be needed. Thanks.
