    Rear suspension - Performance leaf springs

    I don't understand what you are perturbed about. Summit is NOT selling Cat-5 springs for $300. They are selling regular L-10 and L-11 springs for about 10% less than Global West's retail price. If you search for L-11CAT5 at Summit you will get: Global West Suspension L-11CAT5 - Global...

    Over $100k for a Shelby Clone authorized by Shelby!

    It says "expected delivery time to the agreed upon delivery address is 3-4 weeks after final payment is received". I don't think it's a photoshop car. North of 100K is definitely more than an ordinary Shelby clone is worth but how much do you think they have in the car? Decent '68 coupe -...

    Rear suspension - Performance leaf springs

    Whichever spring you use, the bushings will have a significant role in handling (roll) and straight line (wheel hop) performance.

    Rear suspension - Performance leaf springs

    I have Flex-a-form springs and I am very happy with them. Smooth ride and zero wheel hop (and I am running an FE stroker). I am using Global West Del-alum bushings that control body roll so I didn't need a sway bar but a side benefit is wheel hop control. The mono-leaf design of the...

    Rear suspension - Performance leaf springs

    Sway bars don't control lateral flex, they control roll... Springs can control body lean and eliminate the need for a sway bar but that is because of the spring rate. The lateral flex in a leaf spring suspension is not from the springs but from the spring bushings and/or shackles. Rubber...

    347 or 427???

    A TON? Like better springs and shocks? The roll cage was for driver safety not to stiffen the chassis. That was done to the Chargers too. Magazine articles about the movie/car(s) didn't come out until years later. Peoples recollection of what was done probably varied greatly. Yes, the car was...

    347 or 427???

    1. At 1.2 HP/CI, it would be a 23 HP difference if you compared the same displacement. 2. Most charts put the weight difference between an FE and a W at 85-100lbs. 3. An FE intake is huge and weighs over 75lbs. An aluminum intake weighs 24lbs. Yes aluminum W intakes also weigh less but the...

    347 or 427???

    393W beats 427FE? I don't think so. 427W vs 428FE: Testing 427 Windsor Vs 428 FE - Mustang & Fords Magazine The 428 was actually a .60 over 390 or 422. FE made 505 hp, the "W" made 486. Use a real 427.

    347 or 427???

    Steve McQueen didn't seem to have any problems throwing his FE equipped Mustang around corners in Bullitt. How is a non-original bore and stroke combination going to be more reliable than a factory one?

    TKO600 install

    Rear ride height doesn't matter. That only changes the driveshaft angle and that is only a problem if it is so severe the u-joints bind. Unless you have a 4x4 or a donk, that shouldn't be an issue. The pinion angle will not change as the suspension moves up and down. It will change some...

    TKO600 install

    Is that the only option for the T56? It looks like it was put together with an Erector set. I am sure it is a quality product but it looks like a jig or a temporary set up.

    TKO600 install

    That's a good looking crossmember. I wouldn't have been able to modify that one as easily to raise the rear mount. You could use shims though. I think all of the 67-70 mounts will position the trans so it will fit in a stock tunnel (not sure about the 65-66). If you want to change the driveline...

    New 68 Fastback...Project....Maybe

    You say project... so not a daily driver? Do you want something you can drive while you are restoring/restomodding? Most of these 40+ year old cars need a lot of work. The few that don't (besides being expensive) should probably be left alone. My "project" went from paint job to "didn't know...

    TKO600 install

    I think all of the crossmembers are made by california pony cars (or are copies of them). If you check mustang unlimited, mustang depot, dallas mustang, etc, they all list TRA-670-640 as the part number. Cal Pony They're cheaper if you don't buy them direct from cal pony cars.

    I think I got the crossmember from Dallas Mustang. It wouldn't suprise me if there is only one manufacturer, most shops seem to carry them. It fit fine as is but to improve the driveline angle I cut the rear mount off and welded it up higher. Roughly one inch higher at the rear of the trans...

    TKO600 install

    I notched the tunnel support and then boxed in the cut out area to regain most of the original rigidity (and make it look cleaner). I also used an offset shifter which places the shifter about an inch left and back. This way the shifter is closer to my hand without leaning forward or having a...
