So I've been chasing a running hot issue for some time. 74 Challenger 318, 904, mild cam, 600 avs 4bbl. Replaced electric fan with stock non clutch fan. Helped a little. wasn't running a stat so put a 180 in and its just heated up faster but still runs over 200*. Especially in this summer heat. Running a Radiator Express 22" 2 row radiator. No shroud. Would a shroud make the difference? Good 2" from fan to rad. OR am I looking at too small a rad. I thought the stock was 2 row and it was running AC (Sears aftermarket) Back when its was near new. 75 and later...

Thanks
Scott
