I'm gonna take my '70 C10 if I can get registered.
Turbo 5.3. I just got it on the road about 10 days ago, and so far so good. On just 7lbs of boost this thing rips! I'm actually daily driving the truck now, working out the usual bugs and dialing in the tune for driveability. I'll crank the boost up later on...for now it's just fun and basically worry free.
