These old trucks have no cat on them. It will not take long to drive you out of a garage. My 4 stroke smowmobile has no cat and it will drive me out of my 3 car garage with 5 min of idling.
Excellent point haha. I still have no brakes on the truck, need to address that next. But I suppose it wouldn't hurt to pull it out of the garage if I am going to be running it. Just need to get the new gas tank in first also!
