Turk,
In my "What is going on with all the 289's?" post I tried to explain the differences between an original car's weight and the weight of one of our cars today. I was not comparing our car's weight to the weight of a current CSX4000 series car. We just happened to have a CSX4000 in the shop so we weighed it because we were curious and I posted what we found.
The 300 pound weight difference is not entirely attributed to the differences between a Shelby and a Kirkham--but a very substantial portion of the weight difference is in the engine. As I noted, the CSX4000 had an iron flywheel, block, water pump, and heads. That must have contributed to well over 100 pounds of the extra weight. The Kirkham cars we weighed had aluminum blocks, flywheels, water pumps, and heads. The other 150 or so pounds is made up of about 100 pounds of suspension and 50 pounds of misc parts.
aluminum brake pedals
alumnum jack hooks
aluminum throttle linkage and cross shafts
aluminum differential flanges, side axle housings, nuts, pinion flange, mounts (our differential is over 40 pounds lighter than an orignal differential.) Shelby far more iron or steel parts than we do in the differential. I imagine our differential is about 20 pounds lighter than Shelby's. I'd have to weigh them to be sure, though.
aluminum horn brackets
aluminum fresh air can, system
aluminum gas tank straps
aluminum suspension cups
aluminum steering column
aluminum wiper motor bracket
aluminum wiper tubes and nut
aluminum transmission bracket
aluminum tie rod adjusters
aluminum kill switch bracket
aluminum brake hats
aluminum calipers (Shelby uses iron Baer brakes)
aluminum Penske shocks
aluminum wing nuts
aluminum brake reservoir cans
I am sure there are other parts I am forgetting--not counting the latest ones we are currently developing.
David
