Anyone have any ideas. We have to run a stock radiator, my three core isn't good enough and a four core is big, heavy and expensive. Can't run alum. Are there any large tube stock 2 cores. I do have a shroud with the fan tucked inside.

GO TO AN OLD JUNK YARD SEE IF YOU CAN FIND ONEOUT OF A 67 CHEVY PICK UP USALLY LARGE 2 OR 3CORE BUT LOOK INSIDE TO SEE IF IT IS CLEAN IF IT HAS CORRISION THEN IT WON'T COOL VERRY GOOD

make sure your shrouds are making the air go over the whole radiator.

The 3 core was new half way thru season and I clean it every race. I got it hot a couple times maybe I balloned it. I'll check it tom. Thanks

if you have a good shroud,and 1-1 pulley setup a 3 core will work just fine i'd make sure that one is not full of crud like they said and check all things that can cause running hot like wrong timing,to lean or a vacume leak

You said the fan is "tucked inside the shroud". The fan sould only be about 1/2 the distance of the fan into the shroud to pull air through the rad. If it is to far in the high pressure air on the back of the fan hits the engine and goes around the fan and back into the shroud then through the fan again. Make sure it is spaced correctly and that the shacker screen is as far in front of the rad as possable, also run a small peice of aluminum on the bottom of the front end to keep any dirt from comming up into the rad but keep it opne in front of the shacker to allow dirt to drop out.

Hsracer is right. I built an "air-box" between the nose and radiator and didn't need the electric fans under green conditions. That was with a stout 406.

The only problem with this method is that its a little fragile. I ripped the nose off the car in a wreck and switched back to mechanical because I was in a pinch.

The most effective thing you can do after a good shroud setup is like 17j said. 1 to1 pulley setup. Plus a stewart water pump and no restrictor. I guarantee these three things will bring your water temp down more than anything else. IMHO
