Author Topic:   stock radiator on a street stock motor..
posted August 25, 2004 11:38 AM           
Okie... my combo will be pretty close to the following...

350 block, speedPro hyp pistons, camel hump heads (maybe shaved a little since we have a 62cc head rule), open cam rules, 500cfm carb... lets assume that I am not lean/detonating and I have a great fan shroud.

So... is it even worth trying to use a parts store 3 core replacement radiator? It cooled my bomber motor fine... but I'm not sure if it will handle the new motor. I'd rather not pay $200 for an alum radiator when the one I got could do the job.

Should do just fine - ran one that way with a 12:1 355... it may weigh a little more but as long as you're running a "stock" type class and can get the car scaled out with the right %'s and not be overweight then it should be fine...

My 4-core got ruined in a wreck so i borrowed a beat-up alum radiator and the temp dropped 30 degrees,i think they are the way to go.

if you plan on buying new they are about the same price you can find aluminum radiators for 150 new. i've always just ran stock 3 and 4 cores i pulled out of junk pickups and never had a problem tho

17j You must be running a big car too. I run a 73 Chevelle and had a couple of people almost fall over when they saw my big 4 core radiator(out of a pickup)and all they can find for their metrics is 3 cores.

nope i have a metric not sure what this one came out of i bought it used it's a tight squeeze tho i use 2x1/8 in flat down from the insides of the frame rails then 1 in square with saddles on it to hang it from

i ran a stock style last year now i run an alum. and noticed a huge change in temp now i am lucky to be running 190 coming off the track as last year i was running 230
i would recommend the alum style
they also hold more water too
i run a metric and the rad is 19 x 31

The aluminum one is the way to go.Get rid of the weight out front and keep it cooler.
