So I'm not running a super hi-po motor or anything like that. It's a simple 360 in my 65 Belvedere wagon daily driver. Aluminum intake, 4 barrel, headers and duals. Lower compression late 70s truck motor. It runs great but sometimes the gauge will creep up in traffic in the hot weather. Nothing major. I am just looking for a little extra oomf. I'm still using factory wiring and electronics (alt, coil, ballast etc.). What's a decent low amp fan I can mount in front of the radiator? Probably a 16" would work.
