390 and 427 used the same # crank, at that time, but the 427 crank had grooved mains. Pretty sure that's a 64/65 390 crank. I don't know why there's a line through my post. sorry.

 

If it's cast, what makes it a 427 crank vs. a 390? The steel ones are what gets people excited methinks.....

However, from what I could find that price does not appear unreasonable but one should measure twice, buy once on an old crankshaft.....

 

That's a cast crank without grooved mains, so I'm pretty sure it's for a 64/65 390, not a 427. As far as I know, the only difference is the early 427s had grooved mains. I have 3 later model 390s,, that have been rebuilt at some point , and they have C4AE-B cranks, instead of 2U or other 66 or newer cranks.

 

I built a '63 427 engine for a customer about a year ago. The crankshaft that he had was one with the full groove mains. From my understanding the full groove crank was used in the 390HP and the 406 and the 427 used the same crank but without the grooves until '65 when it switched to a steel forging. I had to drill the back of the crank he had deeper to make room for the manual transmission input shaft pilot snout. I just assumed that he had a 406 crank but I'm not totally sure.

 

It's a 390 crank but man.....

people who don't know just should not write more than is necessary.

If a "hot 360" involves the short rods, then by all means, be your bad self with 7:1 compression.

 

Well if you used that crank, the short rods and the pistons that came in the 360, you would have a late '60s 390 with 9.5ish to 10.5ish compression, depending on which piston was in the 360 and the heads.

But it wouldn't be a hot 360 then, would it..... I think I saw that earlier and just ignored it. Maybe.

 

Yes, the proper way to make a low-ish dollar 390 (if that's possible these days). I've put together many over the years (two just last year) like that. Damn they run good! Although, through all of my tear-downs, I have never seen a dished 360 piston so I'm not sure about the "depending on which piston was in the 360" comment. No matter, the thing that makes the FE engine so spectacular is the myriad of displacements/compression ratios that Ford came up with just by mixing and matching parts from a few engines to come up with new ones.

Not a bad price on the crank though if a guy really needed one.

I guess my late (for me) night craigslist perusing should come with a disclaimer that I might not fully understand what's being said and the way you interpreted the listing makes sense. Thanks.

 

That's right !

 

I've been thinking about selling my crank, what's a .010 under 427 steel crank worth, early cup plug design

 

I'm not sure but anything 427 related is generally crazy expensive. A crank or rods probably less relatively speaking than something like a standard bore block or a set of uncracked tunnel port heads.
