They are about 20 cents more expensive than the Spal web site but shipping was 5 bucks cheaper through Summit.

I thought about getting the pace car front spoiler since it looks bigger but I don't know if that would improve anything.

Even better now since June 2014 with the totally rebuilt L-82 355 with AFR 180 64 CC heads and roller cam (.525 lift) with the OEM GM 4 speed with 3.70 gears! The damn thing is really fast…..

You can make this (or similar anyway), homemade. I bought some 4" flashing from homedepot for a home project so I had plenty extra, I also bought 4" vinyl baseboard, cut two pieces of the flashing the same length as the baseboard (I think it's 4' long), then got some self tapping screws, again had them from another project, and screwed the three pieces onto the existing spoiler, the two pieces of flashing and one piece of baseboard. It doesn't look haft bad and works well.

Just a suggestion as I did not see this in the replys. Timing and mixture. Too retards - too hot. Too lean - too hot. after you go over all the common reasons don't forget to check out these two.

Since this thread started 2 years ago and you still have issues. I'd check that water pump. You said it was a new engine. are you sure the water pump isnt for a newer reverse flow(serpentine belt) setup?
On Older car cooling systems
Easy way to remember is that water pumps suck.Meaning hoses to the waterpump will draw the water in. Hoses from the block & manifold are for water being pushed out.

I am reasonably sure the pump is correct. How would I check it on the car. The overheating is making progress. If its under 85deg and I stay under 2500 rpm. The problem starts when I am doing 80mph at 3500 rpm and even then it takes 40-50 minutes of going that speed before I start going past 240 or so on the gauge. It overheats slowly over that time which is how long it takes me to get to work. If I get off the freeway and drive surface streets it cools right back down to 200 or so in a few minutes.

The only way to check the flow is either pull the pump and check the model # or pull the pump and remove the rear cover and look at the shape of the impeller. Most pumps have a stamped steel impeller with straight blades and lots of room for internal bypass. The only pumps I've seen with true curved, billet impellers are the stage 4 Stewart Components water pumps. There may be more out there that I haven't seen.

It doesn't work like this, according to Howard Stewart (the original owner of Stewart Components) turning the water pump the wrong direction will cause very little loss of water flow. The inlet and outlet are in the same place the difference is the shape of the impeller and this will not cause the pump to flow backwards.
