429 crank pics needed
I am having trouble finding a pic of a 370/429 crankshaft rear flange, does anyone have one, and one of a standard 460 crank for comparison? I've read about the differences but not seen any pics, if anyone could help it would be GREATLY appreciated! Thanks in advance.

NumberDummy, in the pic above, the part labelled "7600," that's the pilot bearing? Or is it something else?
Also, I was hoping someone had a 370/429 that they could take a pic of the flange, and post that, and one of a 460, wanted to compare the differences. Or are there any? I keep reading they're different, but no actual pic to show it. Any help guys?

Ok, let me rephrase: does anyone have a 370/429 HD crank lying around that they can snap a pic or two of the rear flange and post it? And likewise, a 460/429 car crank, for comparison purposes? Trying to visually see the differences. Any help would be greatly appreciated.

BTW, if you're thinking of swapping a 460 in place of a 370, be careful of the flywheel balance. I'm not sure if the 370/429 was internally balanced or not, but I believe the 460's were or at least later versions.

Are you looking at possibly swapping a 460 in place of a 370 and need to know if the flywheel will work?

Nope. Looking to swap in a Fuller 6-speed into an F350 w/460 power. However, needed to see the flanges to see if there would be a problem, doesn't look like it. Adapting the tranny for a transfer case is also no problem, Dodge/Cummins guys have done so for years. This was actually, in part, my inspiration for wanting to do this (460 w/Fuller trannyin a pickup).
A lot of people claim internal balance for the 370/429, but it has the counterweight in the scalloped out area just like a 460, so at least the back half of the engine is external balance. At least one flywheel (E5TZ-6375J) claims to be for all three, external balance, 180 tooth and drilled for 11, 12, and 13 inch clutches, depending on the source.
Edit: also, all 385 series engines (car 429 and all 460) built from 68-78 are INTERNAL balance, all 385 series engines with the D9TE block (370/429 truck/460) are EXTERNAL balance, due to smaller counterweights because of the deeper cylinder walls in the block. As I said above, the 370/429HD flywheel has a counterweight cast in. Look for yourself, I'll try to find a pic and post.

DeStroked, probably an FSO6406A, same housing as a FS5306, which was used with a 429, but the FSO6406A has a 0.78:1 overdrive and is rated for 660 lb-ft vs 520 and direct drive, not that a 460 would hurt either one, even heavily modified. I'm looking at a possibility of running the transmission with taller gears, but I'm still doing some investigating.
