hey guys, i need some help on picking a radiator for my roadster. engine is a 400 sb bored 040 over, iron heads, 10.5 to 1 CR, mild solid lifter cam, its a 350/375 HP comp cam. 4 speed. options are mounting the radiator in the rear, no problem, or mounting between front frame rails laying flat. i would like to mount in the front. will one of those speedway sprint car types work? they measure 12 x 17 inches. that will fit, i am not sure about how to use the 3/8 pipe bungs, or what to use for electric fan? any ideas? thanks, pkj
gonna take a fair amount of air to cool a 400 40 over,,run 1 in my vega wagon...12 x 17 is kinda small, would depend on thickness and how fast the water/coolant is moving in it.....
I had a similar set up and the 65 Mustang radiator kept it cool in LA traffic... Just had to flip the outlet to the other side...
i dont know if it makes a differance or not, but the engine is pretty open to the air. very little sheet metal around it. not a long hauler, just a few blast around town and will be in some light traffic. thanks, pkj
that's where you need a good cooling system the most. one 12 X 17 radiator doesn't seam like enough for your engine
With the radiator laying flat in the front, what's gonna make the air want to p*** thru it and cool the water as it p***es thru the tubes? And 12 x 17 is way too small for a 400 in. sbc if it were standing upright and seeing airflow. I'm afraid you're gonna overheat at the second traffic light... vic
