Re: 71 GMC Longhorn, compatible engine and transmition
Hey Truckster,
I do love the sound of that 402, I think it is a badass motor. But it is also kind of rare. I have some worry about getting parts in the future. The truck came with duel exhaust going through actual mufflers. Not glass packs. Mufflers. the thing is quiet, but the sound is throaty, and sounds like it is waiting for any signal to get busy. I will do some research on the transmission. From my searches the transmission is cheaper to replace than to rebuild. Looking underneath the truck, there are leaks from rear end, tranny and engine. So they all at least need gaskets. The truck sit in Indiana for most of the last ten years. It is originally bought in California. I have all that paperwork. Engine starts right away. No issues there, but it does burn oil, you can see it in tailpipes. So it at least needs a rings. It has 173K miles on it. So it is time.
