Other than half the info on that block code is false yeah great thread.
it's a 71-72 429/460 block there are rumors of D1VE blocks bieng 4 bolt mains but they are very, very rare, some do have the thick main webs once again pretty rare, they were not the CJ/SCJ block those were DOVE-A blocks, and all SCJ blocks were 4 bolt mains, some CJ blocks were (most likely they used left over SCJ blocks) some of hte supposed CJs did use the DIVE block.
Also that thread says you can bore them to .080 without sonic testing, do NOT go with that you will find that atleast one cyl will have a non thrust wall that will be thin, with sonic testing you will be able to tell if it can go that far or not but it's not a given, and to bore it to 4.500 bore you will have to sleeve one cyl for sure, and probably as many as 4. We had a block summit last winter at Cuba MO, with Dave McClain doing the sonic testing (Dave has built several engines that competed in the engine masters challenge) we tested 36 blocks of almost every configuration and casting code that you can get (the exception was we didn't have a 370 truck engine block to test) they ALL had about the same thickness walls even the boss 9 nascar block that was present, and every single block without exception had atleast one cyl that was thin on a non thrust wall and at best would end up with a .100 thick at .080 over, and even the D9TE truck blocks had just as thick as the 4 bolt SCJ Dove-a blocks.
Odds are it's just a standard 429 or 460 block take the pan off, and see if by some chance it has 4 bolt mains or if it has thick main cap webbings (if your in doubt take a picture, and I can tell you) other than that there isn't anything special, nor is there anything wrong with your block it will work real good for about anything you would want to build short of 1000hp NA stroker engine. if you have a block with 4 bolt mains than yes it's a good block
BTW that other thread tells the guys to read Tom Monroes book on building big block fords don't waste your money it's so full of mistakes, and flat out misinformation and urban myths that have been repeated over the years, and were a very large portion of the info that is false has originated.

 

hello once again..i now need help with the 429 heads..the stamp says ......dove-0... on the heads.......what does this mean..good or bad ...for me..??? thanks rick

 

hello again..i was wrong ...the heads says ..dove-c..not dove-o..are these good heads for the DIVE-6015-AA block..thanks again

 

they will yeild a fairly high comp ration on that block so you will probably need to run dish pistons to be able to run it on pump gas. Yes the DOVE-C heads are good heads they just bump the compression up pretty good with the 72cc chambers.

 

Other than some of the casting code info being a little off and a typo or 2 there's nothing wrong with the Monroe book. It has good basic engine rebuilding info and some important motor specific info on the 335 and 385 series engines. It's cheap insurance for the novice and even intermediate engine builders can get some good use from it.

 

Bill I actually agree with you but it's the casting info, and some of the other specs that he makes a lot of mistakes on that confuse novices, and start things like several threads that have been on here in the last couple of months, and people take as gospel since it's written in a book that makes me try and discourage people from buying it. It just confuses people and then since Tom Monroe wrote it then people like you or me can't possibly know anything if we don't agree with everything he wrote, adn thus you can't get it corrected in thier mind.

 

I also agree that the casting info is very bad. But like Bill said it is a great book for a beginer building a 385 engine. I have many engine books on fords and chevys, and none go into detail as nice as Monroes do. (I have 4 of his books)
The book does nothing much for some of us but cause disagreement like you said, it had me confused when I first started out because I used it for my first rebuild. if a person could disregard all casting info and just use it for rebuilding purposes it would be a great book to have on the shelve.
I don't think this was the topic of the thread but I just wanted to say I think you both have a good point.
Rob, I hope you got my email, I aprieciate what you are doing.

 

I think were still on track. The question was about a 429 DIVE-6015-AA Block. Thanks, monsterbaby for reading up, so much, on these codes. Best I can tell the Block should really be Cast D1VE not DIVE, but my dad has 1 and it really looks like DIVE. His is a DIVE-A2B and it came out of a 1970 Thunderbird and was dressed as a 429 Thunder Jet Engine with 72 cc heads. It does not have 4 bolt mains. I do not know if any DIVE's or D1VE's were sold as Cobra Jets or Super Cobra Jets. Some were sold as 460's. But, I will say this, if your going to build it for street use, spend as much money on it as you want, it will take it! It is NOT a, "just a plain boring 429 block"

 

I thought the blocks were pretty much the same for the 429/460 except for the 4 bolt one. It's the heads that make all the difference.

 

leaving out the high performance 429s everything is the same between the 429, and 460s except the crank, and pistons. the CJ, SCJ, and Boss 9 are different mainly in the heads except the Boss 9 has a revised oiling system also. Another slight difference betwen 429, and 460 is the 429 could be had with 2bbl carbs, and the 460 couldn't.
Disclaimer like I said that is leaving out any of the hipro stuff, and relates to pass car, and light truck engines only.
