save your money.
things that are going to help are a good shroud, a good flex fan both positioned properly. the thermostat,if it is opening, is not going to make much difference, neither is the spring, and the catch can only helps make less of a mess to clean up.

fix the things that will help and if it still overheats then use the money you saved to buy an aluminum radiator.

the one thing that hasn't been asked yet is how do you know what your temperature is? are you relying on the stock guage or are you using an infra red thermometer? before you spend a ton of money I would check what the actual readings are.

having said that, your problem is at idle not when going down the road so the fan and shroud will make a big difference, other than that the only thing that is going to make a difference is the timing, maybe some water wetter and a new radiator.

one last thought, have you had the radiator flushed? sometimes they are just scaled up to the point they don't work well.

Ok to measure the temperature i am using an afermarket mechanical one. Its mounted under the dash if it matters? And once again thank you for the help putting a spring in the lower radiator hose help enormously with driving around 45 its about 180 instead of 200

well so much for that bit of advice. that spring issue has been hotly debated before, I find it odd that it made that much difference at idle, it should make more difference at higher rpm when the waterpump is sucking more, but whatever it is results that count. I am glad you got it fixed, and I learned something. good job.

ok so... yes it helped but i have a low ratio in my rear end i dont know the rpms cuz i have no gauge but its quite a bit off idle but not far enough to make the tranny shift cuz it has a shift kit in it. Does that make any sense? Thats what i came to
