Aluminium Frame for the SC cobras?

[thorconstr]

I'm looking at a poster on my wall of 1965 427 SC CSX3022. The weight on the poster is listed as 2150 pounds. I don't know how much less an aluminum block and heads weigh, but it has to save 100lbs. So My car should be closer to 2000 lbs.

strictlypersonal Bob could an aluminium frame be built that is the same as the ERA SC one? I don't know what a carbon fiber cobra shell would cost but weight wise between fiberglass and carbon I would think a 50% savings. FFR and Super both built carbon fiber bodies. I thinking also about my heavy pindrives and rims. Should be able to knock 10-15 lbs off each wheel with a BBS. All shafts for the rearend and drive shaft go to either aluminium or carbon fiber. Rear lower control arms for the Jag rear goes to Aluminium or tube design like the IRS ford rear. Still brain farting Bob. The mega millions is just about right for the pickings. Did Jag ever make an Aluminium center housing? Catch you later RickL.

I doubt 3022 was ever 2150 lbs, that would take a LOT of effort to get that low.

The K-bros weighed their original Cobra, converted to SC specs, and it was 2600lbs. One of their KMP cars with alloy everything was only 2200 lbs.

I weighed 4241 about a month ago, and it was 2580. I have a glass body, but I have an alloy trans and rear case, so that kind of cancels each other out. My motor is all iron. My Shelby/Baer brakes weigh less than original Girlings. And I was still 2600 lbs.

On an original COMP car, there's no electric fans, you could have a small racing windshield, you could have alloy heads (rare, but could also be added). But you also have a diff cooler and pump (S/Cs also), and a larger 42 gallon gas tank.

I could see a full boogie comp car maybe hitting 2300lbs.

Cobra's aint THAT light.

I have a full bodied 1959 race car in my shop that's 980 lbs. Now THAT'S light.

Just for reference, the original spec sheet on the 427 Street Car call out three weights:

Dry weight 2354
Curb weight 2529
Test weight 2890

The Comp spec sheet has no weight listing.
