Hi-tech-
Yes we have the same Comp cams hydraulic roller. The power/weight thing is a rough ratio. If my car was 2550 vs 2300, this is a 10% change in weight, so to maintain the same power to weight ratio I would need an extra 10% in the HP area as well or 660. Weight reduction has other benefits as well beyond just acceleration. Braking, cornering, feel of the car, and dare I say fuel mileage are all affected in a positive way when your car is lighter.
I just ordered a 15 lb. battery for the car instead of the normal 40+ lb units. It costs $150, or about double of a regular battery, but saves me 25 lb. Every part for the car I try and find out the weight and see what else is out there. Lightweight Aeroquip lines for the
oil cooler saves another 12-14 lb. It all adds up.
And don't forget to put helium in the tires.
