radiator options for LS swap?

F body rad sucks because it lays down at a 20 degree angle and the rad fill cap is tilted.

Do you want to run a drivers side inlet or dual pass?

I have a griffin dual pass which is clean as the inlet and outlet are on the passenger side so you can get away with a short upper hose vs something that shoots all across the rad. Griffin also has some lackluster reviews for people.

A stock replacement G body part is fine if you are OK with the long upper hose and are OK saving money.

93-97 F body radiator and fans. The LS1 F body guys upgrade to the 93-97 version because it is thicker.
And the cap is not angled backwards at all. It also bolts directly in using the Cutlass top plate.

I would have preferred to keep everything one side. So if I am sticking with the truck water pump, ideally everything on the passenger side.

If look at the Fbody water pump everything would be ideally on the driver side? then this means I need to change the power steering / alternator bracket to match as well, which could be another can of worms.
