i have a 460 with the block code DOVE A and a 429 with the block code D1VE 8015 AA, i was wondering which motor will make more power? i know 460s are VERY dependent on years for HP i haven't found much about the 429s, i know the 460 is anywhere from 365 down to like 200 HP. so yea my question is which motor bottem end will give me the most power (im using the same heads either way)

Thanks in advance!!!!

 

D = 1970s
0 = 1970, 1 = 1971
V = Lincoln

So it appears both are sleepytime pillowbarge motors. Both are two bolt, they might have the same deck of 10.310, but the '70 might be 10.300.

I doubt there are some fantastic heads on one vs. the other.

So, whichever one cleans up the best, with the other as a spare......

As for which one WILL make more power, if you leave one a 429 & the other 460 and do EVERYTHING else the same, I think you could guess, depending, of course, on the heads. If there are some magic heads on one, that could throw the advantage.

Post some numbers off the heads and someone will figure those out.

 

First off the huge change in HP numbers posted had a lot to do with the way they measured HP and the change that was done back in the early 70s with the emissions motors stuff. Next if your rebuilding the motor almost everything that made the drop due to emissions can be changed out (lowered compression, retarded cam timing, etc) Next the rotating assemblies, and the heads can be swapped between those two engines with ease.
With that all said I would look at the blocks and decide which one will clean up easiest (check the bores to see if either one needs bored further then the other one and take the one that will clean up at .030) if they clean up and look about the same I would use the D1VE block and sell the D0VE block because a lot of people are under the mistaken impression you need a D0VE block to support hp and will pay a premium for it giving you more money for your build with a block that will support any HP you plan on making.
The 460 most likely has D0VE heads, the 429 MAY have them with that block casting, check the numbers as suggested if you have D2VE heads on it then you will want to use those as door stops anything else you can use but post what you have and we can give opinions, personally if you have D0VE heads, just pick the ones that check out he best, if you have D3VE heads use those and pick pistons appropriate to get the compression ratio you want adn sell the D0VE heads for the same reason as the block mentioned above.
As to which rotating assembly to use, personal choice, the old saying is no substitute for cubic inches holds true. But it's only 30 and not a lot of change. if your building it to use as a truck engine I personally would stick with the 460, if your building a street rod show play truck use the 429 because it sounds impressive to people when you tell them (the average hotroddre all think 429s are all CJs and will uh and ah about it, even though most are actuallly just passenger car motors)
That should give you a start.

 

lol k now the truth comes out of what im using the motor for . its for my derby car, im just building a motor that will be a good strong runner, not going for a big high HP build,i was just wonderin which motor (stock for the most part) would give me the best hp rating, im probably just gonna run a mild cam, and intake and 4 barrel on it, and open up the heads a bit myself since they are apart. so i've heard that the DOVE block is a "thick web block" which sounds to me that it will take more heat? is that correct or am i going down the wrong line with that. so yea just lookin for the best motor to run stock wise, these motors see no mercy so i guess i shoulda asked which will take the most abuse LOL thanks again for all your information so far!!!!

 

I agree with me235, the D0VE block has thicker webs than the 429. I know this for a fact cause I have a D0VE block and a guy wanted to trade me his 429 block for that fact. They are generally speaking the same block except for the webs. The difference is mainly in the crank and a few other parts.

 

Only one thing wrong with this, a D0VE block can be a 429 block (and is the same casting number used for 460s and for CJ/SCJ) and it is also a fact that some D1VE blocks were cast with the thick webbing. Ok so what... seriously how much HP you have? the thick webbing makes it easier for converting to 4 bolt mains which is cool and a good idea if your running 800+hp but on anything street used it's not neccesary with a 429/460 block.

Remember 429s and 460s use exactly the same blocks until you get into the factory HP stuff.

As to which one will take heat better well the thick web won't help you in the heat dept (might actually hurt in a very small amount but you would need scientific equipment to measure it) and frankly i have never seen anyone that actually can prove they would have benifited from having the thick webbing block. IF you have one fine great, you have bragging rights and I run 900hp on a late model thn web 2 bolt block (and it's still 2 bolt not converted) and it hasn't broke and I am not unusual on these. I prefer the later model blocks because they are 10.322 so you have .022 worth of deck you can remove to get it squared up before being below the factory intended 10.300 deck hieght were as the D0VE blocks are only 10.300 so no room in that respect. You can still deck them but your below the factory deck height.
