Yes and no. Funk made a 6cyl and 8 cyl conversion. The main problem with the V-8 was the tractor was a structural block, the V-8 was not.

One of my friends had both conversions.
Back in the day my great uncle used to order a rebuild kit for I think it was the 239 flat head and an extra pan gasket. It was a cheap way to get two rebuild kits for the N series.
