Hey so you guys are all mechanical and I know one of you guys has some good knowledge of older cars and engines. So a guy owed me some money and I ended up taking his 1965 Galaxie 500 off of him instead of cash. The car is pretty much all original but it does have a different motor than the original 352 it came with, or is it? My problem and question is I for the life of me cannot identify the motor. The guy who I got it from told me he thinks its a 429, someone else thinks its a 390. My question is without removing the valve covers how can I identify the motor? I looked on the bottom where the motor mates to the tranny and saw nothing, the block that we can see says nothing? The Valve covers are blue if that matters. Anyone have any advice??
