76' overheating
Hi all as i go through the forums here i see alot of overheating threads with plenty of solutions but my 76 wont stop overheating on the highway regardless of what i do. Anything above 3200 rpm and the needle slowly creeps up and shows no sign of stopping. I could drive all day on surface streets and through traffic but on the highway i cant go above 95km/hr. I have a gm 350 and installed an aluminium rad w/ electric fan in one. It has the tranny cooler as well. Last year put on the scoop under the engine to get more air into the rad. Ive no idea where ro go from here but any help would be greatly appreciated!

Seals on the radiator? Without them air will slip around the radiator so it needs to be seals to the radiator mount. Where is the temp sens for the fan located? Are you sure you have all the air out of the system?

If you've checked all the usual reasons for over heating. I would check timing, when my car was way advanced, it ran noticeably hotter than usual until I got it timed.
And it only takes a moment/ is free.
