Another overheating question
I have a 67 GTO with original 400, .30 over, mild to hot cam, 650 Edlebrock (though I need a 750 Holley), aluminum non AC radiator with a shroud, overflow, and an electric assist fan on a manual fan.
So, It's gotten a lot better but since adding the shroud, aluminum radiator, overflow and assist fan. But last week I went to a car show that started around 2:00 pm. We staged at a parking lot and then everyone paraded to the street they had closed off. While I was driving slow and waiting for my turn to park in 85 degree weather with the electric pusher fan on, I got up to about 235 and still rising.
I've adjusted the pump plate and have good flow.
My question is, can I add a larger radiator? I would prefer to modify my radiator support instead of buying the AC version. I don't have AC now but plan to add an after market package some time.
Has anyone cut there radiator wider to fit a wider radiator?
I hate dealing with heat issues.
