On the drive shaft stock weight is about 15 to 20 lbs and the aluminum is about 8 to 10 lbs. Im not sure about the fuel cell.

Thanks man. Only a 7-8Lb difference isn't worth $200+ dollars, if your numbers are right.... I guess ill see about the fuel cell weight difference now.

The driveshaft is rotational mass though. An almost 10 pound decrease in rotational mass is a lot more significant than just stationary weight. It's not just weight reduction, it allows the engine to rev faster as well. I would do that and f*ck the fuel cell. You won't see any performance gains from a fuel cell.

So you telling I should forget about the fuel cell and switch the drive-shaft??


Note that the weight-loss is only 8-10lbs according to Badboty.

Brad89IROCz is right...rotational mass is always a better way to go than stationary weight. There is a coefficient of power loss per pound of rotating mass that is greater than the power gained per pound of stationary weight shed.

As far as the cell, the rule of thumb is loss 100 lbs, get a tenth (on the quarter). So I'd say screw the fuel cell and go with the driveshaft.

What other performanc eparts have you put on your car? You wouldn't notice the difference on a stock car.

This is a new-project. I had originally bought a few parts for a plain 350 motor, but I stumbled across 350Vortec which is rolling motor, so know I must start from scratch........But i was plaining on trying to lose some weight by buying some light-weight parts such as, fuel cell and a alluminum drive-shaft, which don't seem to be worth the buy.

I think that the drive shaft would be a good buy. The aluminum is stronger and lighter so you will have less of a chance of anything happeneing and you can increase your rwhp a couple points probably. I think that it was Chevy High Performance magazine that put on on and gained 2 rwhp off stock motor so if you start putting more to the ground it would be a good idea.

You can go with either a JG1 aluminum driveshaft from a 3rd Gen or an aluminum shaft from a 4th Gen LS1 car.The earlier 4th Gen LT1 aluminum shafts had quality problems from what I've read.They interchange between 3rd and 4th and between automatic and manual.And you can usually find one for $100 shipped(or less).You would only need a custom shaft for high HP applications.
