If money is not an issue, then get a Griffin aluminum radiator, an electric fan, and an overflow tank.

RE: overheating problems?
Thanks for the help guys. I wasn't sure if it was just hype but it looks like people swear by aluminium—good to know. I'd like to add A/C one day so I just want to make sure the cooling situation for the emgine is bulletproof first.

I had a glance here and it looks like Fluidyne doesn't cover my year: '67. so it looks like I'll be forking out the dough to Griffin!

RE: overheating problems?
You could look into ron davis radiators...theres some good radiator manufacturers out there, if your going to buy a new one. Shrouds are a necessity. How about the water restrictor?

RE: overheating problems?
Hey,
I am having a similar problem, My 69 has a high performance 302 with a pretty big cam in it. I was running the stock coolant system and was running really hot. Last week i upgraded to a 3+ row radiator a high flow water pump, and 2400 cfm electric fan. I also put a a new mechanical fan that sits about 4 inches from the face of the radiator and put a 4 inch fan shroud on. Now even with all of that the car still runs right below H, it is almost touching H. I am afraid to drive it because i dont want to kill it. I also had a 195 degree thermostat in and downgraded to a 180. Still there is no real difference. the only thing that i noticed with the new coolant system is it takes longer for it to get to H as oppsed to before. I also have the stock radiator cap on, it is old and rustty, but the rubber looks good underneath, Could that cause a problem, or do you think i should get a spacer for the fan to get it closer to the radiator. Any suggestions will be appericiated!
Thanks for your time!

RE: overheating problems?
Having learned the hard way....don't trust the guage in your car. Mine was running just blow "H" for the longest time. I finally broke down and purchased an infrared thermometer and found out I was running right at 180 which is also the thermostat I have installed. Come to find out that my guage needed to be re-zeroed and I also adjusted the calibration. It requires pulling the guage but there is a good article about guages in the FAQ if you are interested.

I thought the engine runs hotter at idle??? when it's moving, it'll go down 15-20 degrees.

There are just so many possible culprits when trying to nail down overheating. A good rule of thumb is to do the cheap stuff first: get a recovery tank and replace that radiator cap with a brand new "closed system" one, and get yourself one of the Prestone backflush kits. Those couple of things shouldn't run you more than about $25 together - and just may do the trick.

I have a '67 with a newly rebuilt 302 roller (.030 over) with a holly 4 barrel. There's a 4 row radiator and the fan shroud is in place. It's still running SUPER hot.

Will an aluminium radiator really help? Do you think I should go with an electric fan? Any recommendations on brands? I kinda thought everything was right but it's not helping at all. It's 100+ where I live and drive to work every day. Money isn't an issue so overkill solutions are welcome.
Thanks,
Coop
