How did you get a 460 in a Chevy? Only way would be a 383 stroker. Just saying, I’m pretty sure you meant a 454. The 460 was Fords big block.
You’re probably right. Actually I just looked it up. It was a 496 L18 engine—the van was a 1-ton extended wheelbase loaded up with every option. At the time, it was our family car and we used every seat.
I’m not particular about manufacturers, and I’ve had decent cars of all sorts, but that vehicle was really nice; however, I’ll never buy another GM product. Maybe a Tesla next—just kidding. God bless and goodnight!
