    73-87 Radiator ?

    Did you change radiators when you swaped in your LS/Vortec or did you just rig the hose's to work? What radiator did you go to or how did you make your stock radiator work. I'm just getting started and I'm trying to get everything togeather. Also are you all running Elec fans or what. Any help is greatly appreciated.

    radiator

    i don't know how much diff your truck is from a 68 but im running a 2005 vett radiator from pro radiators on ebay 146 bucks works for 6.0 or 7.0 engines plus it is light (13lbs) , has built in oil and trans cooler and is about 3 in narrower than my stocker, height is perfect. only thing is you have to run a water bottle caus it does not have a built in cap but you can get one off of pretty much any newer car. your stock tranny and oil lines hook right up

    I used the stock 6.0l hose with the diesel radiator.
