Quick question
I am taking my 68 Chevelle to one more cruise in June b4 I yank the old 327 out & freshen her. This car is stock. Right now, If I get on it hard at Op temp, it fills the overflow & tries to puke coolant from the overflow tank. I have done nothing to this motor yet. I noticed it had a fresh w/p on it when I got her about 6 months ago. It is totally stock; except a mild cam. Runs cool... I wonder if the previous owner put in a high flow HD pump??? it looks stock. It is probably the small 2 core rad; manual trans. Whatcha think?
