I tried the retard, thinking I maybe too far advanced but it's back to 28 total. The carb is as rich as I can get it and after some instructions from C&S got the idle to 1000 rpm's. The sender is mechanical and seems to be correct accord to the infrared gun I picked up. I'll try and go with a totally enclosed dual fan setup. I have 1 but it's pushers and I haven't got room for it. I have about 3" behind the radiator in most places and a few that is close to 2". If I can convert the pushers to pullers I would use this set up. Talking to a couple of racing friends that has been around the block, I'm told the CSR water pumps aren't good for any street driving as they don't flow enough water. I'm told a mechanical hi flow pump should cure the problem. The only problem with that, is I don't have the drive setup for the supercharger and will have get 1. This thing is driving me nuts and broke. I like the looks and the fit of everything with my current setup. I hope there's way to keep it and keep the car cool. Thanks for all the input guys.
