I have a big block '89 K3500. But that's too new to be a Stovebolt so it doesn't count, but I did drive it today.
I also have a 454 I'm planning to run in the COE I'm building.
And then I recently acquired a Cadillac 500 that I think will go in the 1-ton Dually that will be a '49 or '50 AD or maybe a '53 GMC depending on which cab and title I choose.
I like big blocks.
