460 blocks
I have questions about the different 460 blocks maybe I can get some learnin' here? I have 2 1970 429 blocks, pretty sure I know that's the standard to build, short of a CJ or SCJ block. I also have a 1978 460 from a van, and a 1995 also from a van with efi. I understand that the later blocks have a taller deck height? Can they be milled down to match the earlier units? Is the deck thicker only, or are the water jackets also raised? Taller deck means different intake manifolds? Are the later units worth trying to use, or just wasted cash? Thanks!

Yes, later blocks have a taller deck.
Yes, they can be milled down.
I don't know about the water jackets.
Same manifolds, the decks aren't that much higher like the difference between a 302 and a 351w.
Later blocks will work fine.
What kind of HP goal are you aiming for? I currently have mild build with a D9 block and it's at 450hp.

Thanks Doosenberry, you didn't say whether you had decked your block or not? Do you order pistons for the taller deck? Or just take that measurement into the calculation for compression ratio? Looking to build a torque motor for the 95 Van. Use it to haul the dirtbikes, and camp in. Racks and such like an outfitter rig, lifted to drive the backroads, not 4X4. Be nice to keep the efi, I understand it can run up to 450 or so HP? Is that another whole story? Or bigger injectors and keep all the sensors? The computer will tune? Maybe just easier to go with an old fashioned Holly mixmaster?

My block was what they call "zero decked". You install the crank, rods, pistons, and find out how far "in the hole" the top of the pistons sit then have that much material removed so that they sit flush with the deck. My compression ratio is somewhere between 9.5-10:1. I don't recall the exact number, but it definitely needs premium gas to run.
I would head over to 460ford.com or 429-460.com if you have a lot of questions. I'm not knowledgeable enough to give you that kind of insight, but there are quite a few legitimate engine builders over there that can advise you. There's also a lot of info already posted if you use the search feature.

10.322" from '72 on, right?

It's also true that the D9 blocks have deeper cylinder walls due to the cranks being externally balanced. If you try to put an internally balanced crank into a D9 block it's going to hit a lot of things.

You say you have two 1970 blocks. Look at the casting numbers if they are D0VE blocks they are 10.300 deck and have the same main bearing webs as the Cobra Jet and Super Cobra Jet the difference is they don't have 4 bolt mains. If you look at a C9VE or a D1VE you will see there is a lot more metal in the D0VE main webs. You used to be able to find them in those big old Mercury's and Lincolns but sadly most of those cars have disappeared into the crushers.

Most engine parts manufacturers, I have found, use 10.300 for their compression calculations. Contact them before you order parts to make sure though. Then calculate your compression using your head's cc's. If your block is 10.322 you can add about 5cc's or have it decked to 10.3"

A bit late here, it got sidelined for a bit. I have a D1VE block, deck ht 10.300. I found one side pistons at .035 below the deck, the other side was .032-.037 ft to rr, so I am having it milled by .010. The Speed Pro flat tops (1 VR) are .005 higher than the stock at 1.890 so they should be at .020 below deck, with a .040 head gasket it gets a bit better for the quench area on my 75 cc heads. Eddys 60679. It should come in at about 10.5:1 comp.
Now I'm looking for cam suggestions. It's going in a F-5 Cobra with a T-5, Astro gear set, 3.55:1 rear gears. Going to run a carb, probably a 770-850 CFM Vacuume secondary, on a New Performer intake. As I understand there are some hood clearance issues for the 385 series in these cars. Might be the wrong forum to ask, but info transfers, Thanks.

Oh yeah, complete engines. Have a couple 460s as well. latest block 1978. This one still had the nylon toothed timing gear, and it was in great shape. I have never seen one come out of a motor this good, not that I would ever reuse one. Crank is nice, just chamfering oil holes and having it polished after the balancing. Also looking for details about radiusing the oil flow into and out of the pump, and drilling a drain hole to lube the dist driven gear. I will clean up the casting rough edges when it comes back from the machine shop.
