Re: BBC overheating
That sounds good.
Are you up for a crazy idea?
My 70 SS396 I had back 30 years ago tended to run a bit warm too. Around 210 on the highway. I read about mounting an air dam directly under the rad behind the bumper. I retrofitted (with a couple mods) a dam from a 75 nova. It hung down about 2 inches below the bumper if you looked from the front.
It worked great. Dropped my highway temp down 15 degrees.
The theory behind it is the dam creates a low pressure area behind it and the hot high pressure air from the engine compartment escapes more readily into that low pressure area.
Better air flow thru the rad is the result.
I’ve made them on other trucks from some strap iron and a length of plexiglass.
Just something to experiment with.
