I agree. You don't need as much torque in a lightweight car. I will encourage you to get some common Cobra curb weights, as everyone tends to think that a Cobra weighs about 2000 lbs. Some of the kits, especially when you add in a full tank of gas, driver, etc, will hit closer to 3000 lbs.
Let me remind you that I've never stressed a high horsepower or high torque engine. What I have stressed is that you forget about picking a random rpm number that you want to achieve and concentrate on making the car usable in the rpm range that you will be in the most.
You can not have a 289/302 that will have great manners and power at 1500 rpm and still make peak horsepower at 7000 rpm. It's just not going to happen.
An engine that makes peak horsepower at 7000 will not only require a 7500 (or higher) shift rpm, but the camshaft required to make peak horsepower at that rpm will pretty much insure that you won't have much at off-idle rpms.
Again, I'm just trying to help.
