Wow Train, no shortage of suggestions but as far as the Suburban goes, I'll realte a short story.
3-4 yrs ago when I owned my '03EB we had a real snow storm, like 18" of it. I left my home and drove over the Bay bridge to Kerry home. Her community was not plowed so I drove 18-20" of virgin snow to her Townhome. an hour later, the local MD State policemen who owned a new suburban tried following my tracks, he couldn't, he bottomed out. He and several others were working to free it when we left. Again because he was stuck on my tracks, I had to drive around them, on virgin snow....the Expy never missed a beat but that big ole Surbana wasn't doing so well in the white stuff!
Train, you're old school like me...and JE and a few others here. We grew up with V8's, we like them and know they are largely unbreakable. Just keep in mind that all those young kids have, for the past 30 years been working on better stuff than we had to work with. That's why a rather small 211CI engine can reliably produce well over 365HP/420TQ for 100's of thousands of miles.
The world is changing my friend, what used to be, is no longer....in the 80's, I HATED turbo's for many valid reasons....yet today I own a turbo charged bike(ironically a modified factory '82), a supercharged car and my twin turbo truck. It's like that really old Monkee's song.....I'm a believer<LOL> ....mainly because there is no difference in how long they last or maintenance.
Good luck Brother....
