By the way the lower house is shot!!!
Thats a lot of time, $ and work. By the time you do all of the work with tax you will be close to $100. Might as well just pay an extra $100and get a new rad for peace of mind. Then you dont have to worry about it again.

Yes and no, I think time on a toy is not that big of a deal. It's really not about saving 100.00 here and there but more than anything its about teaching myself that some stuff is salvageable. luckily I am in the position to "throw" a 100.00 at it to see if I don't need to replace a radiator if I do oh well I'll do it. The car is not a daily driver thank god so no rush but A 6 pack of beer and hanging with friends is a good day!

Have you checked the timing? Retarded timing will cause it to run hot. Make sure the vacuum advance is working and hooked up to a manifold vacuum source on the carburetor (unless you are concerned about emissions, then leave it on the ported vacuum source).

ok finally got around for an update on this, flushed the radiator, put a new thermostat in new fluid, cleaned between the condenser and radiator and its still getting hot...I'm going to try the extension on the spoiler but I'm thinking a new radiator is in order. I am thinking that a radiator from autozone or oreilly will be sufficient but I'm not a vette expert by all means most of my knowledge is stuff with 2 wheels. So the question is a new stock radiator or an aluminum (engine is stock)

Have it rodded out at a radiator shop.
The lower hose MUST have a spring to keep it from collapsing.
Use a Robert Shaw stat that fails open.

Take it to a radiator shop - have it cleaned, rodded etc. Money well spent, and a lot less of it than going with an aftermarket part.

Just for what it's worth, I'm a believer in cool. If you are going to take your radiator to a shop, ask what it would cost to re-core it with a 4-row core. I did that years ago and paired that with a 160 thermostat and I can run a long hill at 80MPH on a 95 degree day and never get over 180.

Then your old radiator probably needed to be rodded out.

Glad to hear it's solved.
