Re: Cooling a 69 Copo
We actually had trouble bulding heat in our L-72 as it got later in the year. The culprit was the stock rebuild (10.2:1 compression) and the added racing fuel. As the air started getting cooler, I had to switch over to running premium (about 90%). I let the car cool for the first round at the Pure Stocks in Stanton, and subsequently lost about 2 mph...the next 2 passes were run with it really warm, and the mph came back.
The next L-72 will be the exact opposite[img]/ubbthreads/images/graemlins/naughty.gif[/img]!

[img]/ubbthreads/images/graemlins/beers.gif[/img] Actually my orange car ran a little hot. The guy before claimed to have the rad redone, but I'm beginning to wonder. If your really concerned about cooling, redo the rad with the coolong fins on 3/8 centers instead of 1/2 inch. Did that to my white car, and could'nt get it to run hot no matter what! Peter
