429 / 460 block Deck Height

I have a D1VE block I'm using for my 460 build (55 F100 Project).

It is my understanding that the "Deck Height" on 429 /460 blocks was changed at some point to assist in reducing compression ... back when government mandates were ruining our toys

Based on this casting number can anyone tell me if this block would have the lower or raised deck height ... and ... If I'm all screwwed up and this makes no sense, feel free to tell me that too

Ford raised the deck in 72 to lower compression. As I recall it went from 10.300" to 10.322".

I have so many different blocks I don't even bother to check them anymore. I just tell my machinist to square & deck it .020 out of the hole. Problem solved

With this casting D1VE number and knowing that the engine was a 429 from a 72 Ford LTD ... would you say it is most likely my block is the "Lower" deck height?

I am just wanting to some reasonable info to have a decent idea of compression ...

I'm running the 460 crank ... KB Flat tops with about a 4cc valce releif ... and D2VE AA heads.

Knowing the exact compression is not critical on this motor, but I'd like to have a good "seat of the pants" calcualtion at least.

Nope. Wouldn't bet on it being a 10.310 and definately not a 10.300 unless you know for a fact that some has decked the block in the past.

D1VE-A2B blocks were used for a number of years past 1971. Pretty sure up to the D9TE block came out in 1979.

Hey Larry, unless you've already done work to those heads, I have a better set you can have. They are D3 heads. Still of lower compression, but they are still of a quench design. The D2 head is as open as a 2v Cleveland and is very prone to detonation. Let me know.

Larry,
I checked the Keith Black website. If you are thinking about the flat-top (KB #137), that piston will give you 9.7:1 with a 97cc head (like a D2VE?) and 10.2:1 with a 91cc head (close to a D3VE). The piston will still be 0.020" in the hole on your 10.322" deck height, so you won't have much quench. That sucker will probably ping.
I'm no 460 expert, but I've been a-readin' the 385 forum, so look out...
Like Luv70sFords says, the D2VE has the worst chamber of any 460 head. You'd probably do better with the D3.
You might think about using the TRW #H535P piston with D3 heads. It will give you 9.14:1 with an +.030" overbore. Run some decent cam (215-220 intake duration with 110 LSA?) and it shouldn't ping.
Or if you want some punch, zero-deck the block with either flat-top and some ported D3 heads. You'll have around 10.5:1 with good quench, but you'll probably need a fairly healthy cam for pump gas.
Like I said, I'm no expert. Check out the 385 forum archives for much more info. Good luck.

I know the pistons are just under 4.0cc on the valve reliefs ... I'll cc the ehads once I get them off the engine they are currently on ... then I'll check the piston in the hole number ... Then I may be shopping for gaskets.

Anyone have a "book" number as to the cc's on the chamber for these heads?

I may be shopping for head gaskets on this one to get the thing down to more like 9.5:1
