Thanks for the info guys,definately save me some time.
I work part time at AZ and know the guy's at both NAPA/Oreilly's here in town as well (I work on their cars alot :) )
So I shouldn't have an issue comparing the different W-body radiators more closely or side by side.
If I need to update then I will definately,and i'm with you guys and thinking it's a no-brainer and I need to.

I did plug the SC/TB coolant ports in the manifold,but I opened up behind the crossover plate as well so there should be plenty of flow.

I have spare sheetmetal as well as plenty of header wrap to wrap it all up if I decide to go that far.
The heat shields are a given though once I get the headers in.

Finally got all the parts/gaskets in tonight for my little sisters geo so hopefully be done with it by tomorrow and get started back on the impala this weekend.

I would definitely like to know what you find after comparing a few different radiators side by side. Having a low cost radiator upgrade available would definitely be nice. Most of the supercharged radiators are just $190-200, which ain't bad considering that most aluminum high performance radiators are $400+. I did a little looking on advance's website last night and found basically the same thing with their listings. The supercharged GP's and Regals list thicker radiator cores than the N/A applications, but the Impalas and Monte Carlos list the same radiator for both applications. I don't understand why the difference, but at least the listings seem consistent.

Gotta get back to welding now. I'm probably making the bracket beefier than needed, but I plan on using it several times so I'd rather it be overkill just to be safe.

IIRC, the N/A 3800 police impalas got the S/C 3800 radiators...

Had a few minutes to check last night.Autozone lists the A2710 rad for both 2004 impala na/l67 as well as the grand prix na.
The 2004 gtp is another that is an 1" versus 5/8" as mentioned.
No part numbers available for police package.
The gtp rad is special order,so can't compare at AZ.
Fortunately it is a parts store,and I have customers with them. All my customers seem to like me so probably won't mind popping hood to measure either.
Gonna search on gtp forum as well,the info is out there i'm sure.

Stopping by napa to help one of thier guys with thier truck and visit with mechanic buddy there in a minute. I'll see what they list.
I plan to email the place I got my aluminum fiero rad off ebay.
I got one of the american eagle/champions and I really like it.
A small bit of trimming is no problem,I just don't want to re-engineer the front end.

You can also look at a 2004 Buick Regal GS radiator. It is 1" thick also, but it carries a different part# than the GTP radiator and is a little cheaper. I was also looking around last night and found a pretty nice aluminum radiator on the ZZPerformance website. It's huge at 1.4" thick and it only costs $299, which ain't bad if you ask me.
