The 292 would be a cool engine if you score one. I found websites that sell rebuilt 292's for $1200 bucks. Of course, that's a stock rebuild.
350's run so incredibly well and offer the best bang for the buck. But you lose that original look.
In a car show about a year ago, I entered my truck along with several really pristine AD trucks. But mine was the only one with the stovebolt engine. Mine was far from perfect, but it won the people's choice award, despite how beautiful the V8 AD trucks were.
From that, I draw the conclusion that most people prefer the old-fashioned look of the Stovebolt engine.
The 292 would give you that. But I agree with the above, if you plan on driving it a lot or using it for work, the 350 might be the more practical approach.
Bottom line, it's your truck, and your choice.
I'd advise going to a good car show that might have a few different AD trucks on display.
