Cooling question, running too hot.

Well I hate it but I did it. I got off early today because of rain and rode up to Griffin. I took my old radiator with me to make sure to get everything squared away (didn't need it). The sales guy Benji Durham is the one that helped me. He said that as soon as they get one of those built for a Mopar that it gets gone before they stock it in the warehouse. They was building one for a Mopar as I was there but it was already spoken for so he couldn't sell me that one... even though he walked into the back just to check and see if he could sneak and sell it to me. But we walked over to his desk and he took down all my info. He said that it will look close to the original type radiator and I could paint it black if I wanted. It will be a 2 core with 1" tubing (400-600 hp) down flow (not cross flow) for $495 + tax OUCH!. I asked if cross flow is better than down flow and he said it doesn't matter one bit. That the only thing changing is the direction of the flow. I always thought the cross flow are better for some reason. I read Griffin FAQ section and it says the same thing. They have also 2 core with 1.25 tubing for I believe it was $595 which is 600+ HP. They are going to have to build it so I asked if they could locate the top tank inlet closer to the middle and he said no problem. He said it will not be directly centered but it will be closer than it was. Oh he asked me what was the car doing and I told him that on the HWY it would get to 210* He told me that if it was getting hot on the HWY that my radiator is too small and if it was getting hot in stop and go traffic that it there is not enough air movement. So in theory I was having both but that's going to change. ok shroud... he told me that 98% (even big blocks) mopars did not have a shroud unless it was AC equipped. So I don't believe our cars suppose to have a shroud but I'm going to try to find one. He told me to try Bouchillon performance (something like that) or bring in a shroud and they will tack on mounting brackets to fit the shroud to the rad. They will make them a little on the wide side so I can center the shroud to the fan after I mount the rad. He didn't say that but I am going to tell him to do that to give me a little room to move the shroud up and down. He said he will call me to pick it up in about a week or so. I hate spending that kind of money but I can't drive my car without it is the way I'm looking at it. Now I've got to find a shroud.

Here is the website http://www.bouchillonperformance.com/FanShrouds.asp

I'm thinking of getting the 22" fan shrould and let Griffin weld some tabs on to make it fit. I just found this a few minutes ago so I'm still brain picking what I really want to do.
