So i have a small leak in my 02 radiator, was gonna try u pull it but looks like all they have are v6 cars. Do lt1 radiators fit in ls1 cars?

Yes. The LT1 radiator is actually considered to be an upgrade in LS1 cars.

93-97 there was a radiator difference between the LT1 and the V6 cars (V6 was smaller), but 98-02 the v6 cars got an upgrade to the same radiator the LS1 uses from what I understand.

I'd throw the LT1 (V8) radiator in there. There's a couple of holes you have to plug but the radiator is thicker, meaning it cools the coolant better. In addition, the LT1 radiator is cheaper than the LS1 radiator and you can find write-ups galore on here.
