I got a 98 gmc sierra 4.3 v6 vortec has oil and trans cooler lines. Would I need to use a 5.3 radiator or could the 4.3 v6 vortec work. It’s a stock 5.3 nothing done to it
The 4.3 works fine, if anything get a trans cooler later, but the obs radiator looks clean and you can get some electric fans from a 2003-2006 Chrysler Pacifica they fit perfect you just got to make minor adjustments.
Yes you can use a lot of factory parts. Don’t let anyone tell you any different either

Yes you should be able to use your OBS one with the fan. Good luck with your project you are going to like the power that the 5.3 has 😊🤙
