    jmc hydraulic clutch

    The distance between the hole for the brake pushrod and the hole for the clutch pushrod (which is where your clutch MC will mount) varies. The '69-'70 guys seem to be able to run any kind of booster. The '65-'66 requires a bell crank booster, of which there are several on the market, including...

    Shocks and leaf springs (how do they work together)

    To test if the shocks are causing the harshness, either take them off or pop them out of the spring bracket and wire them up so they won't hit the bracket, and go for a ride. I'll bet you'll find most of the harshness is gone. Whether Bilsteins will cure it, I don't know. There's also the...

    What Performance Flat Tappet Hydraulic Lifters are out There?

    Do not use the Rhoads lifters, or the Crane High Energy, with that cam!!! The only reason to use these "fast bleed" lifters is to provide vacuum at idle, so that you can operate power brakes with a high overlap cam. Yours is not a high overlap cam. These fast bleed lifter make your engine...

    Teardrop Hood

    Maier Racing makes the stuff that Mustangs Plus sells. Year One has a carbon fiber one for about $500 that's cool.

    Vacuum advance.. timed/ported or manifold

    I see what Max Power is saying, and it makes sense: if you set your base timing with the vacuum canister attached to un-ported vacuum, you will lose that vacuum source on tip in, which will pull out timing and which will cause a stumble. Thing is, I thought you were always supposed to set base...

    Power Brakes swap - distribution block?

    I don't know about a '68, but the distribution block on a '65 with the standard single reservoir master cylinder has no internal valving. Therefore, when switching over to a dual reservoir system you can continue to use it to split the lines to the front brakes, after plugging off the port to...

    Vacuum advance.. timed/ported or manifold

    There is no good reason to run ported vacuum in preference to unported. For some reason the "fancy" way seems to have gained popularity, but the reason you run vacuum advance is for improved fuel economy at part throttle, and at part throttle ported vacuum and unported are identical.

    what's wrong with this shelby?

    You're right about the underriders being incorrect. All '65's and the first 200 or so 66's had the overriders. That looks like an 8" diff to me, too, which would also be incorrect. Could be a replacement of the axle along the way, which if it was a quickie repair prior to 1970, when...

    A/C not running Cold

    You could try a simple experiment: disconnect the heater hoses at the engine and run a loop between the connection. I had a prob with the AC in my '70 Cougar and the problem was the water flow valve on the heater hose was rusted through, so hot water was going to the heater core. OTOH, on my...

    Snake Eyes

    Better fix it. With a 427FE S/C 746 HP 790 Torque this is going to be the only view of this car most of us will ever have.

    HP Calc.

    I think the answer is, yes, the hp-based ET calculators are whacked. They will generally tell you that the same hp that will achieve a 102-103 trap speed will also give you a 12.99 ET. The truth at the track is, only if you get a monster hook is a low 100's trap going to be good enough for...

    HP Calc.

    The formula is rear wheel hp = weight x (trap speed/234)^3. Therefore, the higher the weight, the more the hp. 3000 lbs may be too high for a '65, maybe not. Flywheel hp = rear wheel hp/.80 for an automatic, hp/.83 for a stick.

    67 Convertible suspension complete replacement, Advice?

    You got lucky. As I posted already, the same Maier 4.5 leaf springs gave my kids' car the ride height you see in the pic I posted, and gave my neighbor's '66 coupe the 4 x 4 look. I replaced the Maiers with a pair of Mustangs Plus 4-leaf "mid-eye" "one-inch lowering" springs and got the 4 x 4...

    67 Convertible suspension complete replacement, Advice?

    Here's how my kids' '65 looked with Maier 4.5 leaf springs, with some Pro-Motorsports 350-480 coils trimmed slightly to match: Look familiar? The funny thing is, I sold these springs to a neighbor, who put them on his '66 289 coupe, and they rode about two inches too high.

    67 Convertible suspension complete replacement, Advice?

    These suspension packages from Maier Racing look killer. I would get all three. For a vert I would stick with the lowest spring rates: Spring, Leaf, & Shock Package (500, 600,or 700 Front Springs, 160 Lows or Highs, Bilstien Shocks, 165 or 200 Race Leafs add $50.00, Koni shocks instead of...

    Lowered the front end - results

    I'm a member of the "cut 'em off" school of coil springs. Most warnings are based on the idea that shortening a coil increases its rate. While this may be true, it's nothing you'll feel on a seat of the pants level. I believe the Shelby drop will give you that last bit of ride height that...

    Will these wheels tuck?

    You're right. I got my wires crossed. It happens a lot when you're -- what? -- 180 out. What a great idea. The first kids on the block to run the late model "Bullitt" rims were paying as much as $200 for machined spacers. Of course they also had to change the bolt pattern too. OK, now that...

    Will these wheels tuck?

    The less the backspace, the more the "tuck." No way does this rim have a 4.5" backspace: That's a late model rim and it will require a fairly expensive set of spacers to fit a classic.Just think about it. The seller also says it's got a "0 mm" offset. Offset plus backspace equal rim...

    Need to raise the front end...

    One inch spring insulators will increase your ride height by a little more than one inch. Mustangs Plus has them in poly.

    Replacing rear springs

    At the front end, the lower control arm bushing is also subject to binding. Mark your eccentrics, so you don't lose your camber setting, loosen the pivot bolt, and go for a spin around the block. Having said that, I would be surprised if the front end would have that much effect on the ride...
