Yeah, I'd leave the 429 alone...dunno how much more rare they are, guess it depends on the application. But yes, you can go with a 514...can't remember what the stroke length is off the top of my head, but a 514 retains the factory bore of a 460. Alot of guys go with a 521 which is a .030 over bore. I think you can use the stock block all the way up to a 545...maybe maybe maybe even a 557 stroker.

429-460 have the same exact bore. its the crank thats diff. think 360 vs. 390. if you have a 429 cj or super cj then the heads are awsome. stock 429 heads are not the greatest. most guys buy the cobra jet heads for those blocks.
and to steal a quote. "in a hundred years is anyone going to care?" i say if you have the motor do what you want. if its a "thunder jet" 429 its just a plane jane 429 nothing rare or special about it. i've got a buddy with a 429cj that he's putting a stroker kit in. i asked him why and his answer was simple. why not? who will ever know? its all internals so unless you dive in and check it no one will know.

I'd imagine the reason some folks care is because if it is one of those 'rare' 429's, there are folks out there looking for originals and will pay top buck for them. So my viewpoint is why molest like that when as you said, there are plenty of 'unrare' blocks out there that no one will care about. Kinda the difference between hacking up a 69 Boss 420 mustang vs. hacking up a fox body.

well if its rare sell it then take the money and buy a 460 and make her a monster. 514's are not that uncommon any more.
i say build a monster 8.5:1 comp motor and drop an 8-71 on top... with a touch of the laughing gas... hit the gas and after your eye ***** come out of the back of your head you'll have one hell of a smile... :l

I don't think there is any difference between a 429 block and a 460 block in terms of casting numbers. There are differences in those blocks over the years though. Something like nickel content and thin vs thick webs if you're gonna add four bolt main caps. Which I would do if you're gonna stroke it.
I bought a rotating assembly for a 521 for $1200 a few years ago.
Stock stroke is 3.85" the 514/521 stroker crank has a 4.25" stroke. as mentioned the 514 is a std bore and 521 is .030" over.
They are not cheap to build at least when done right. but 700 hp is very capable and 1000hp is about max
I've never assembled mine yet. but when I do:
SRP Forged pistons -
Scat H beam Rods
Scat 4.25 Cast steel Crank - not as good as forged steel or billet
4 bolt main caps and a bottom end girdle - prevents cap walk
Recommend
Ported Stage 3 Kasse heads - these thing like to breathe
Big single plenum intake
Lots of big Carb

idk if its anything special i doubt it but it was out of a 70 torino according to the guy, d0ve-a block, with d0ve-c heads, also came with stock intake and carb, took one head off and every thing looked pretty damn good i personally thought that i could probably drop it in my truck and run it as is, but at first i thought well just rebuild the 429 with a mild cam or something but then started reading about 514s i i really thought that would be cool

i have a 429 tj and was wondering how to go about the build i want to get over 400
hp on pump gas. do i need to go roller drive train should i buy alunium heads. what pistons should i buy? all the machine work has been done on the original block and heads. should i port the heads. what exactly do you do to build a 514, is it a different crank?

yeah its just a stroker crank and rods and pistons. 400hp out of one of these motors is way too easy to make. hell a good cam, intake, carb. and some minor head work and you'd be over 400 hp. or you could just pump he hell out of it with nitrous...lol just dont plan on it holding up if its stock...lol 600hp out of one of these motors is pretty easy to reach as well its all about how much you want to spend.

least the tranny will bolt up to it. ported is pretty good but a set of ford racing or edelbrocks would be really nice. i think world products makes heads for it too. well its like we said the 460 and the 429 have the same bore so...no real differance if you make it a stroker. its just what ever it started life as. i still say 8.5:1 comp with an 8-71 i cant think of a better way to spend $12k just make sure you have stronger drive shafts...lol in all reality you can get a 600hp motor super easy with a good kit. but you'll still need to beef up the rest of the drive line. i have a buddy who has a 68 F250 with a monster 460 stroker. 3 yrs ago at the truck pull event he was the only one who was bouncing the throttle. near the end he laid into it and left his drive shafts on the track. i think maybe 2 other trucks had nearly as much power as he did.
