i'm finishing up my swap right now and trying to make sure i've got all the parts i'll need. does anyone know if i'm using the stock (LT1) radiator and a stock LS/fbody water pump, what radiator hoses will i need to use? i've got stock LT ones now but if i need something else i want to get it now!

thanks guys.

do you have access to the car you got the engine from? Maybe you can just take it's radiator. Worse case, look around at Rock Auto to see what hoses look close enough to work. I ended up buying a radiator anyway because i put a screwdriver through my old one by accident (note to self: screwdriver != chisel). It cost something like $109 delivered...

there has to be a a handful of people that have done this swap, what did you have to do?

a lot of ls1 fbodies swap in lt1 radiators...maybe try searching for people who have done that swap in the cooling section here?

^ i searched a bunch of those posts and nobody mentions what hoses they use, so i'm guessing stock LS ones will work?

i guess I'll buy a set of both stock LT and LS and return doesn't work.

in case anyone ever runs into this thread with the same question, you need LS1/f-body hoses.

both radiators have inlet/outlet in the same place, but the water pumps are different.

I am running stock Ac delco Ls1 Fbody hoses. If using a Lt1 radiator you have to plug the engine oil cooler port. Also look for a 98 Fbody upper hose if you are not going to run a power steering cooler. Later models had a two piece upper hose for the cooler.
