It has a 1946 flathead engine. Looks solid otherwise.
“I have a 66′ CJ6 for sale. These are VERY rare, and collectors Jeeps. Most went overseas for Safari work, while the rest went to the forestry departments in our country for service work. This Jeep has 55,000 original miles and came from Nebraska. It has a Go-Devil flat head four cylinder engine that came out of a 1946 Jeep, and has 13,000 miles on a rebuild. The Jeep has a hardtop and a three speed transmission. It runs and drives nice, and is a lot of fun. It comes with the Jeep Odd-Fire V-6 engine with bell housing, starter, and headers. The Odd-Fire engine has a street performer intake and Holley carburetor. If you have any questions, feel free to email.”
