Default LT1 radiator for LS

I'm in the process of swapping in an LS into my 94 Z28. Can I still utilize my LT1 radiator for the LS motor? Can I use the same upper and lower hoses, or do I need to get hoses made for the LS? Thanks in advance.

Nope, hoses are fine, just have to plug or cap the couple
of unused heater hose ports (?) on the LT1 tanks. Other
than that, fits right in and cools better.

Thanks. Are the LT1 oem radiator better than the ones for LS1 oem?
Any other suggestions are greatly appreciated, thank you.

If I remember correctly, I have noticed probably a consistent 20* difference in temps from swapping to an LT1 rad. It made a big difference.

EBay sells aluminum radiators for 150 for fbodies. No reason to reuse old stock junk.
