[QUOTE="Lamar, post: 801827, member: 16675"] Dear group; I've used both brass and aluminum radiators and while aluminum does all right, but IMVHO brass is still the best for offroad use. I am having cooling problems of my own right now and they are opposite of the norm. I can't the water to rise above 150 degrees F. I have a 4 core brass rad, a stock 2F heavy usage water pump with 2" port, a t-stat housing with a 2" port and a 180 F t-stat. I've verified the temp gauge and it's right on the money. So I'll prolly end up going with a 1.5" WP and t-stat housing and rad ports. I ran that beast at over 120 KPH for 3 hours today and it still won't get warm. Last week I kept it floored in 4W-LO in heavy mud for 14 hours and still no luck, it never rose past 150 degrees. I've advanced the ignition timing to the point of knocking, I've used hotter plugs and leaned it to the point where it won't idle and the damned thing still will not rise above 150 degrees. If I could get a higher temp t-stat I would try that, but 180F is all they stock here. I guess when I decided to build a cool running motor, I built this one a bit too cool.
