So i'm converting my early 70s 360 to a 390. I installed a C3AE-E (1963) 390 crankshaft. The base/lip of the crank snout looks smaller than the 360 crank. I have a Cloyes 3012k timing chain. According to Cloyes, that timing set should fit on a 63 Ford with a 390. However, that same timing set on Summittracing says it won't fit. Argh! When I look at the crank snout with the timing gear on, it looks like the woodruff key only fills half way. comments please!

Are 63 cranks that different for later castings?

 

I recommend you post your question in the FE forum. There are lots of FE gurus who will be willing and able to answer your question. Or PM Bullitt390.. he's quite knowledgeable.

 

FE's used two different crankshaft sprockets, '58-'63 cranks used a 3/16" woodruff key, '64 and later cranks used a 1/4" woodruff key, the only exception is the '63 390's which used both woodruff keys, so in the latter case you'll need to compare the parts.
