360/390 question
I know the only true way to tell the difference between a 360/390 is to measure the stroke. Well my old engine is not assembled but its really hard to tell where the top of the stroke is just by looking at the cylinder walls. is there any way to tell from the crank if its a 360 or a 390? I was about to take this engine to scrap but I wanted to double check before i through out a good 390. when measuring the cylinder It looks like the stroke is 3.78 which is a 390 butnot 100% and Im just using a tape measure. anyone have some info i would appreciate it.
Thanks Tim

<!-- google_ad_section_start -->If there's a "half moon" cutout on the flywheel flange it's a 360 or a '65 and earlier 390...
No "half moon" cutout on the flywheel flange it's a '66 and later 390

Montana, there is not half moon cut out on the flywheel flange just a ushaped notch cut, and red road thanks for the measurements on the piston rod but measuring with a tape measure its hard to tell. I really think its a 390, which is good. should be eaiser to sell.

1958/64 FE engines have rounded valve covers without holes for oil caps/smog valve. There's an engine oil fill tube on the right front side, it's made as part of the valley pan.
2U = 390: 1966/71 Passenger Cars & 1968/72 F100/350 (C6AZ-6303-A crankshaft).

the engine came out of an 75 HB, but thats not to say it wasn't changed. Well I checked the crank and there is a 2U but thats it. So now im not sure.
