Would my dual snorkel scoop be affecting my cooling at highway speed?
My distributor was locked at 35 total advance. 456 gears and 5500 stall at 60 mph the temp was 180 steady. Hard to get it over 180 with the new B-cool rad. But I had and electric pump and fan so the water flow stayed consistent.
I also have a snorkle scoop it is sealed to the carb. Maximum holes in hood without sealing it to the carb was two holes 4 inches in diameter. air escaping out of the engine bay was always a problem. This is why old school racers lifted the back of the hood.
At one time I was having cooling problems so I made an air dam to put more air through the rad. I came to find out my coolant tubes were swelled from over pressuring the rad when testing for leaks and the air flow was restricted.
I bought a new rad. and left the air dam in place. At about 120 mph or above the front lifted under a hard pull in drive up a hill. Once the front lifted the whole car came up. Scariest day of my life. I thought the trans went it was the rear tire lost traction.
Here is a picture of the air dam I installed. Took it off and never used it again. I gave it to Dave for his Valiant. Also here is a video of a friends car 'Frank' who didn't have pressure relief holes in the interior. It blew the drivers door out at the hinge at around 200 mph turning him into the wall
Pressure builds higher than you think when you get up in speed.
