It's a 352 in a 65-66 F100. The angled oil filter, hand choke and flat top valve covers are the indicators
was not a pickup i recall. thanks to all for pitching in. scott
Sal, I've had a '65, '66, and a '67 F100. All were original 352's with manual choke 2100's, alternators and the squared top valve covers. This photo is definitely a pickup from those 3 years. In '68 the pickups got a 360, 2100 with an auto choke and the rounded, Powered by Ford valve covers. I just don't have a picture of any of my old rigs to verify it
Take another look Sal, I can see the rear of the mounting flange, and I can't see anything that looks like the secondary throttle plate activator rod that would be on a 4100
Are you sure you are not looking at a 2100?
