I will have a 20,0XX mile LT1 radiator for my 1994 MN6 car available this fall if anyone is interested. I'm going with a custom Becool for my 454 LS7 install. Tis thingis in gerat shape. I had a window sceen/frame made when the car was new and placed it in front of the radiator to block out bugs and rocks, I just clean it out with compressed air, has kept it inVERY good shape wih coolant changes every other year 50/50 dexcool. -=MIke

This is one of those things hard to get here

Do you think if you ordered an LT1 radiator from napa for a 93-96 fbody, would it be single core?

Mine is a 98 as well. Pretty much just a drop in replacement. The core is a lot thicker of course so it will be a little tighter fit. As mentioned before there is only one place you need to block off and the is the bottom left looking at the rear of the radiator. Just make sure is a 93-96 LT1 radiator because that is the big core ones. GM Part #52466004. Good luck brother.

Thanks!

I checked the GM service manual and their description is pretty complicated.
They say to remove the whole assembly from the bottom... engine cooler, AC cooler and fan shroud

This means empty the AC system

Can you use the integrated trans cooler as an engine oil cooler? I already have external trans coolers. Could you just go to an autoparts store and get a radiator for a 95 Camaro?

I did my whole swap from the top. Just push the AC hoses out of the way to remove everything. I dont know about using the tans cooler as a oil cooler. I have no idea about the fans for an LT1 because I am using the procharger supplied fan for my application but I would think they are similar.

one of the tanks( can't remember which side) is different from lt1 to ls1. i think only the 93-95 lt1 rads are bigger, 96-97 are the same width as the ls1(don't quote me)

Little more update. I went to the track last night and the car temps never went over 190. With the LS1 radiator the temps use to be around 200 or more. I even let the car idle after the runs in the staging lanes and the temps never rose over 180. I am running a 160 thermostat. So I am really pleased with the results.

could you please provide a picture of what you did to block off the extra hole i believe at the bottom driverside of the radiator. I put an LS1 in my 96 and need to know this so that I can use my LT1 radiator on my car. Thanks.

I will try and get one for ya. I pretty much just put a cap on there. A more permanent way would be to epoxy the hole shut though.

Here is a real close up pick of what I used to block the hole off with. This is looking at it from directly below. It is the little nipple looking thing. I just put the rubber cap on there and used a clamp and went about my business.
