UPDATE: **SOLD** Was $1200.
It’s doesn’t look like a standard Willys head, but could be a Willys engine. Col car.
“1953 Hudson jet only made in 53 and 54 has a flathead Willy’s that turns over, needs new floors and rockers but can be found on eBay”
Why someone would replace a Hudson 6 with a 4 cylinder L-134 Jeep engine is beyond me, but that is a Willys(maybe Kaiser Henry J) engine.
