I suggest you get your stock one recored.I run a stock 318 2 core in my race car with a worked over sb 410c.i.Or you could try useing a clutch fan too.

what does the rest of the system consist of? the worlds best radiator can only do so much if the fan/fans are not up to the task. if you are running a mech. fan does it have a shroud? if electric what are the flow ratings?

also what thermostat are you running? is it a high flow unit? is the system running full of water with all air burped from the system? it all works together.

im running a 185 thermostat and believe I have all the air out of the system,any extra pointers on that would b appreciated to. im using a syock fan with a after market shroud that just is basically a piece of metal around the radius of the fan I wondered if that was part of my issue too thanks for all the responses

I have a built 340 with a six cylinder rad and it is ok as long as I do not get caught in traffic. I would say that you might want to try a proper fan shroud! I also run water wetter in my rad. Not sure if it makes a difference but it can't hurt

I have my stock 340 radiator recorded ,shroud and clutch fan it never has had a overheating problem but i have heard the pre 70 radiators are not as good but all parts need to be working to spec.

When does it get hot? Sitting in traffic or out on the road going 50 mph?

I have 67 barracuda 360 425 hp champiuon 22inch 3 core radiator a home made schroud, 180 stat. Mine usuall runs 175-180 in the summer on a 90 degree day in town it may go to 195, I also have a electric fan up front set at 200 degree but it usually only comes on during a hot restart on a 100 degree day. I think even a 19 inch 6 cyl rad will do the job if its cleaned and flowing right.
