Lose 34 Lbs - 1970 Stage1 GS Diet Recipe #1

In the pursuit reducing the front-end weight of my 1970 D/SA Stage1 GS I started with cooling system. The stock set-up made use of a factory four row radiator with internal tranmission cooler - although the tranmission cooler was blocked off.

In stock eliminator aluminum radiators are not legal in the earlier muscle cars so a little creativity is in order to reduce the front end weight.

Here are the steps that would make Jenny Craig herself proud:

1) Weigh your car prior to making any modfications - I recommend also recording the weights at all four corners if possible.
2) Drain the entire cooling system.
3) Call "Cool Craft Components", 4423 District Boulevard, Vernon, CA, 90058 and order PN 005330 68-71 GM,&BUICK X-FLO 283/8" - 11/2 SD1 1/2 SPXP12.
4) Make sure that when you order this unit you make sure and tell them to build without the internal transmission cooler. (You could also find a 2-row stock style from a 4-spd 350 car but they are hard, usually worn out and not built with todays technology)
5) Install the new radiator and refill the cooling system with fresh juice.
6) Scale the car again.
7) My car was 34 lbs lighter due to the new radiator being lighter weight and the reduced coolant volume in the cooling system.
8) At the race track I did not notice any cooling probelms whatsoever and speculate the larger more efficient design is probably as good as the ancient stock radiator.
9) Note: I do run a Mezziere electric water pump and electric fan in the car.
