Shelby Aluminum

[steelcomp]

The last 427 I built was for a cobra project that I was doing. It was a chassis up brand new G&S, and it was an all alum. Shelby. Found a BRAND NEW nos steel crank (still in cosmoline), Eagle rods, Venolias (10.2:1) Comp solid, Shelby heads that I ported and did the valve job on, Manley valves, Dove rockers, Manton p/rods, Blue thunder int and a Holley 750 db. with an MSD. I talked with Mike LeFevers at Shelby (sp) throughout the project and we were looking at the mid 500 hp range.

You guys with these kit cars don't get the fact that you have about the worst chassis design going for getting power to the ground. Some of the live axle cars do better, but then they are even less a cobra replica, just a bastardised copy to me. I remember guys bragging how their car could "smoke the tires at 60 mph!" BFD. If you had any kind of properly engineered suspension, you wouldn't do that! It's nothing to brag about. The Arntz/ Butler is about the only car out there with any kind of thinking about the chassis engineering, and I've had this arguement with tube chassis guys vs. back bone, monococque, all types. None of them work, but I have seen a true 840 hp BBC in an Arntz w/slicks and the Jag rear turn 9.40's, and drive home.
You wanna try that in your car?
HP in these cars has nothing to do with how fast or quick they are, and some of you guys that are putting this kind of power in these cars are literally taking your life in your hands. I wonder how many of you would even know what 600 hp feels like when it's REALLY hooked up.
