So for the past month or so I've been shopping for a new pickup. 3/4-ton gas engine, ext. cab, short bed, 4x4. Pretty specific list of requirements, but it's not like that's an uncommon configuration. About 10 years ago GM/Chevy put a Vortec 8.1L engine and Allison transmission in their 3/4-ton pickups. Big-ass gas motor, perfect for hauling with. I believe 07 was the last year of them. Not "new", but not exactly vintage either. Went to a GM dealer in town yesterday, about 10 minutes from my house. Parked my bike, walked in, receptionist greeted me and I asked to speak to a used truck salesman. () Friendly lady meets me at the desk, we go back to her office. "Hi, i'm Mule, and I'm shopping for a used truck. Looking for a 5-8 year old 3/4-ton gas pickup, extended cab, short bed, 4x4. Been a Dodge guy most of my life, but some of the GM's have piqued my interest. What do you have?" "Is there anything specific you were looking at?" "The 8.1L Vortec's have caught my eye." "You mean 6 liter?" "No, I mean 8.1 liter. Vortec 8100's. 3/4-ton truck, 02-05ish, Allison trans.... 8.1." "GM doesn't make those." :huh "You're telling me GM never made an 8.1 liter gas engine?" "I've been here 6 years and I've never heard of it. Let me go ask another salesman." "Nope, the biggest they made is a 6.2 liter." "Do a google search for '8.1 GM' and learn something new. I think I'm done here." At which point I grabbed my helmet and walked out of that place laughing. Stopped at another dealer, and as we're browsing their inventory for 8.1's I told the salesman there about the previous dealer. He laughed, and asked "Alpine?" "Yep, that'd be the one." I guess they're known in the area for being a truly awful dealer. And the 8.1 I test drove later that day must have been a 6.2 liter.
