block & head ID
This is supposed to be a '73 429 but the more questions I ask and the more I look around the more confused I get. The heads have the code C9VE-A on them, so what does that make them, exactly? The block ser# is 3Z529908 with the letter S stamped under the 52 and on the passenger side of the block it says DIVE-A2B and on the driver side front of the block it says 101 with an 8 under that. I know that this engine has been rebuilt at some time in the past but that's about all I do know for sure. Can anybody help me out on this????? Part of the reason for my confusion is because it has 429 head gaskets and a 429 water pump but, according to my Chilton's book the firing order is supposed to be 1-3-7-2-6-5-4-8, but it fires in the 1-5-4-2-6-3-7-8 which is for the 255, 302, 351, & 400 engines. I don't have any idea what parts to even think about buying to rebuild this thing.:-staun

If it has seven valve cover bolts than it is a 429/460. Eight valve cover bolts for clevelannd/modified engines, windsors have six while FE's have five bolts. Drop the pan and find the crank casting number to tell what you really have.

I didn't know about casting #s on the crank and I'll be sure and get them as soon as I do drop the pan. At this point however, I am hesitant about opening up the engine and letting the humidity start getting to the inside parts just yet. Right now, I'm hoping for some kind of ID from the casting #s on the block and heads. I know that may not be possible but, I'm hoping. The problem is not yet knowing what I'm going to build it into. I know that I'm not going to keep it stock but, right now I'm trying to get a handle on what the different parts are going to run me for the different power modifications. See if this is a '72 or '73 429 then it is only rated for 208 or 212 hp. If it's a '71 or older 429 then it's rated for 320 or 360 hp. With the newer versions having 8.5:1 comp. and the older ones having 10.5:1 comp. and the only other differences I can find between the two versions is a 0.002 larger bore on the newer and a larger main brg journal dia. on the newer and the older version also having stronger valve springs. problems, problems,...WW

[updated:LAST EDITED ON 25-Dec-02 AT 02:18 AM (EST)]wesley958.... What you should have there is a 429 or a 460. 429/460 fires on 15426378. The heads are a 1969 casting and the block is a 1971. Crank casting for a 429 (4U or 4UA) and 460's or (2Y, 2YA, 2YAB, 2YABC or 3Y). 429 and 460 use the same head gaskets and water pumps. Main bearing journal dia is the same. The only difference between the blocks are the deck height. A 71 block should be at 10.322 If you need any more help just post it.

Allright! I knew someone out there would know what those numbers meant, exactly. That means I should have the 360hp engine instead of the 212hp model. If Chilton's screwed up the firing order like that I wonder what else in this book is worthless. Is there a way of telling what compression the pistons are supposed to produce, I mean by some kind of markings on them. "According to the book" this engine should have 10.5:1 compression. Before I pulled the engine, I ran a dry compression test on all of the cylinders and the highest one was 170psi after three compression strokes. Any idea what kind of pressure I should have? About all I can ever get out of anybody around here is "as long as they're all within 15 or 20 lbs of each other you're good to go". You ought to see the blank looks when I ask "what if they only pump up to 50 or 60 lbs"? Also, would you happen to know what the casting numbers should be for a stock crank? Hey, you said to ask...:-) WW

wesley958....Some times those Chilton's will misslead you, try to get those old Ford servicing manuals, there much better. The HP droped in 72 so you have a keeper there. About the pistons, well if there the stock units there will be cast number on them. 429 and 460 pistons are different from each other. There won't be a compression figure on them. What you need to do is find out exactly what engine you have, 429 or 460. The quick way to tell is by pulling the oil pan off and look for the crank cast number. The crank casting number for a 429 are 4U or 4UA) and 460's are (2Y, 2YA, 2YAB, 2YABC or 3Y. You find them on the front end of the crank, 1st or 2nd crank throw I believe.

That D1VE block was used up till the mid 70's. To know for sure what year the block is you/we need the Date Code which is under the intake in between the lifters.I have a D1VE block and is a 75.I also have a set of C9VE-A 429 heads with a date code of 8K28====68 nov28

OK, I'll try to get out there and pull the oil pan off in the next couple of days, since it's supposed to get back up in to the 60s later this week and see if I can find those casting #s on the crank. I don't expect that it's the factory crank though because, I think the engine was rebuilt some time back by a place in Houston called Precision Engine Rebuilding. At least I'm sure the heads were since they still have that co's tag on each of them. I guess we'll see soon enough. Naturally, I will also assume that the pistons are not factory either, at least for now. Then again it may have just gotten a ring job and rebuilt heads. I don't have any info about that co and they aren't answering my e-mails. Maybe they're just busy??

I was wondering if there were more #s on the block some place. I guess when I pull the oil pan and look for the casting #s on the crank I'll go ahead and pull the intake and get those #s. Would you happen to know if there are any more numbers on the heads that would date them more specifically? What about the intake? Are there any factory iron intakes that would be as desirable as say an Eddelbrock aluminum midrise? What about carbs? I've got a Carter 650 for a Ford and the Ford 4bbl that was on the engine and a large Holley single pump. I hear bad things about all of them but, I'm wondering which one will give me the most trouble-free service, especially if I decide to put ram-air on it or, maybe turbo charge. Also, I don't have any idea how to post pics. DAMNIFIKNOW-WW

you can tell more from the date code than by the casting numbers.just about all the major parts have date codes.You could have what you think is a 460 going by the casting numbers,when all you have to do is change the crank and pistons and now you have a 429(the rods are the same).Thats the difference between the two.So get some date codes and well go from there

I'm baaaack and now I've got numbers coming out of my ears. The crank says 4UA on the 3rd counter-weight, lobe, lump, whaddyacallit. All of the rod end caps say C9AE and under that, 6210-B and on the other side, CF11. In the valley under the intake it says something that looks like an underlined 2 G17 and in a circle it has the numbers 18753. This symbol (design, casting mark?) is also on top of the intake. Ok, now what guys???DAMNIFIKNOW-WW

I can't swear that's an underlined 2 but I'm at a loss to describe it as anything else. Yes, it does have flat top pistons with a relief for the valves. Would these be the 10.5:1 compression pistons that the book specified? If so, then I should be looking at the 350 horse engine, right?DAMNIFIKNOW
