69mach1build 22 Report post Posted May 15, 2018 I have a 427W running on E85 with AFR heads that makes 590hp. 13.5 Compression Street/strip vehicle. I am looking for a cost effective aluminum radiator. Or even a factory radiator if it would be adequate for my needs. Suggestions? Quote Share this post Link to post Share on other sites

Anything you can do to keep the temps down is going to help. I got a 24" 3 row View my build photo album by clicking on the image Quote Share this post Link to post Share on other sites
Vicfreg 772 Report post Posted May 16, 2018 I have a DeWitt direct fit radiator, in their black special coating. High quality, US built, aluminum radiators, and they look like the original. Quote Share this post Link to post Share on other sites
Vicfreg 772 Report post Posted May 16, 2018 Oh, I have a 393 stroker. Ran the engine and radiator combination on my engine test stand in the summer in NC, and was fine cooling wise. Quote Share this post Link to post Share on other sites
barnett468 418 Report post Posted May 16, 2018 the absolute best value in a rad is the coolcraft aluminum high efficiency with a multi pass option. the best one would be a custom horizontal multi pass one but they are expensive. you also need a high flow water pump to get the optimum perf out of this rad. a brass milodon high flow t stat is the best if you run a t stat. this being said, you don't need a big rad if you are only going to run it at the race track.

1969vert 55 Report post Posted May 16, 2018 Barnett is right... My 427w is using a champion MC338. Was using stock 24" 3 core from years ago... Using the 3 core the temp would rise from 160 to 195 down the track during the 1/8th Now 165 start 170 to 175 finish.. Hi flow pump and such..147deg. stat flex fan and shroud. Your E-85 should help out on the cooling .. Have a buddy with a small truck and he has a hard time keeping temp in it on E-85.. E-85 is going to be in my future soon... as soon as a station gets it near me.. Quote Share this post Link to post Share on other sites
