Radiator Selection
« on: March 22, 2021, 05:56:59 PM »
If you've done an LS/LQ swap in your 2nd gen curious to know what radiator you ran and what alterations were required.

I'll be going N/A. A few folks have recommended the "becool" radiators/fans. They are upwards of a grand if not more. Looking for something more economical.

You don't "need" an LS swap radiator. I ran my stock 1976 radiator when I did my LS swap. It is nice however to get a dual pass radiator that has the outlet and inlet on the same side. Especially if you are running an 98-02 Fbody LS1 water pump.

1976 Trans Am LS1, 6 speed, C5 Brakes, LS1 rear 12" brakes, and much more...SOLD
My Build:

New project: 1968 Camaro LS6, T56, Speedtech, Hotchkis, DSE, Z51 13.4" front brakes, LS1 rear disks, etc.

the stocker works, the biggest issue is the hose size from the LS to the factory 70s rad on the upper hose. I would recommend Cold Case or Champion, they make both stock units and LS swap units. I used Griffin before and had every single one blow the core out without explanation. you can also run the stock 4th gen F body rad for easy hookup.

I used the stock radiator from the 98 TA I pulled my engine from. It fit great with little modifications to the car.
79 Trans am low buck LS swapped
79 Formula 301 (Work in progress)
67 RS Camaro (This one is next)

I used the OEM 1981 301 turbo radiator for my LS1 swap, no issues in florida heat

Monuted electric fans on it, controlled by computer. The fans were from an 02 fbody i believe.
