Ok we will just agree to disagree on this one. But for reference I consider $100 for a set of stock factory heads stupid money unless your talking PI or SCJ heads then I might consider going all the way to $250 for a rebuildable pair.

 

Wow, you are tight fisted! The cheapest I've seen bare CJ castings for is closer to $950. That doesn't count some of the stuff on eBay, that's a fixed price for a bare D0OE casting. IMO that's stupid money.

 

I have driven a vehicle with OE 1976 heads....then with a set of DOVE heads...and the DOVE heads win hands down. There is a vast difference. Currently have a line on a good set if anyone is interested.

 

And those two vehicles were otherwise identical right? like same weight, same gears, same tranny, same carb and intake, same cam oh wait non of that stuff would make any difference cause the DOVE heads are so good they can beat everything else. BTW according to DD2k which may not always be right actually isn't usually says that the increase in hp by upping hte compression the amount that putting on a set of DOVE heads is a grand total of 12hp with no other changes and for that 12hp your paying how much? and having to buy higher grade of gas at how much more? and do you know that for every 2 degrees you have to retard your timing to make it run decently you are lossing 2-4hp so it doesn't take long to loose every bit of gain.
Oh you do know there is no such thing as a 400 M right?


Ok I get the hint and will shut up let hte myth win out just like the myth of D8TE 4 bolt blocks, since some mag printed that the 4 bolt blocks are around and plentiful and DOVE heads a major power increase it must be true right?

 

Hay monster I am glad to see you stick up for what you beleave to be right.I really dunno much about the heads on a 460.I just used the ones that came with my block and i beleave them to be the dv3e.does that sound right?anyways I love the reading here and what you say makes sence wich i do know enough to understand and am glad this thread is here cause i am trying to figure out what i can do to get more oompfh outa my 466.

 

Yes...I'm aware there is no 400M....My mistake, something I've learned from this website. Would like to edit my user name......
And yes, it was the same vehicle....same carb, intake, cam, headers gears yada yada yaa. Maybe it was only a 12Hp increase...but it was enough to blow the doors off of a built 55 Chev with a 327 I was only adding my personal experience with these type heads. I've also heard the D00E-R heads are better. True??

 

yes that is very much true that the DOOE-R heads are better and IMO they are as good as or better than the edelbrock alum heads non CJ version, but they are getting real rare, and pretty high priced.

 

D0OE heads are 429 CJ heads. Thay also have small combustion chambers but much larger valves & ports. The same castings were used for the SCJ heads with minor changes to the valvetrain setup.

 

Slap a set of D0VE heads on it....what else???

Sorry Monster...I just hadta say that

Note to self: Don't poke the bear!

Truggy yes you probably have D3VE heads, port the exhaust side expecially work on getting rid of the thermactor bump in there, also make sure the block is square decked and if possible bring the pistons upto as close to you can to zero deck. Next I know you like that 270 cam but you really do want to look at one with a dual pattern something like the xtreme series of comp cams.
Or of coarse you could just slap a set of DOVE heads on it cause that will make more power than a blower.<a href='http://www.smileycentral.com/?partner=ZSzeb008_ZNxdm824BXUS' target='_blank'><img src='http://smileys.smileycentral.com/cat/36/36_11_16.gif' alt='Blah Blah Blah' border=0></a>

 

Actually it's a tightly kept secret that Bob Glidden ran stock, unported D0VE heads on his pro stocker but when they started costing the "stupid money" he couldn't afford to run them anymore so he retired.

I read it on the internet so it must be true!

 

OK , after reading all the DOVE bashing, It HAS to be DOVE season right??
Sorry , just could not resist...
I notice you keep talking about running the Dove heads and low octane gas. But what about running 93 all the time?? I have a 429(have not pulled to check stroke) that is a DOVE block and DOVE C heads with a 2 barrel. I will soon be upgrading to a Edelbrock intake and a 770 Holley and a dual pattern cam for towing. I am not afraid of running high octane gas or additives.

Or should I just sale the whole setup on EBAY and buy a later 460??

 

As I believe I've mentioned in this thread I run my 1970 429 4V with D0VE-C heads and a D0VE block on 92 octane with no problems. However I don't have an issue with the occasional light rattle under load. I've never put any additives in it.

If you're already planning to put a different cam in it then look for one with a long duration to alter the dynamic compression ratio so that you allow the cylinders to bleed off some of the compression. In addition upgrade your cooling system with a better radiator, better water pump, 160 deg t-stat and consider having the intake manifold coated with ceramic header coating to keep the A/F mixture cooler.

 

My comments about the dove heads is your going to have to run 93 (or something close) but in addition to Bill's suggestions, I would suggest polishing the combustion chambers, and making sure there are no sharp edges either on the heads or the pistons. Plus make sure you have a good quench distance, and in addition Scott J. has been having pretty good luck cutting quench channels in the heads and improving detonation resistance. As of yet no one that I know of has actually done a dyno test to see if this is helping power at all but does seem to help the ability run a little lower gas with the same compression. I am going to do this on my A460 heads bucause we can't see any harm in it and it might add just a little better mixing of the fuel/air as it's fired.

 

Thanks for the quick replies!! Few questions, longer duration... Is that a higher or lower number ?? Brainfade here... I have always heard it refered to as higher or lower duration... I am installing a 4 core radiator next week and installing an aluminum FMS water pump. An ACCEL ponts conversion kit is on the way as well. I allready installed an ACCEL Super Coil that I had in my spare parts bin. I have not towed with this motor yet in stock form but it has great vacuum and I just tuned the 2 barrel with the vacuum gauge and it runs better as the previous owner had the carb idle adjusments way off.

Last but not least?? The deck height change I keep hearing about on these blocks... What does that effect when I want to convert to a 460 later on??
