Check this out... Radiator
The LS1 Radiator has a 7/8" core thickness, Some LT1 radiators were 1". I managed to find a radiator on Ebay with a 1 1/4" core for LT1 cars. Which BTW is a drop in for LS1s. Depending on the year, you may have to cap the Coolant level sonsor Hole which SLP did with epoxy. SLP sells these guys for $300.
This Guy on ebay sells them for $90 shipped.
