HELP rebuilding motor
so i have a 429 that i will be building this winter, i would like to make 400+ hp, should i do a 514 stroker or should i build that 429 really well and put aluminum heads, i figure that the stroker kit and the heads are close to each other money wise, so i can do one or the other, which will get me the power i want, the truck will be a cruiser for the most part but would like to own some ricers and ponies as well, and occasionally take it to the strip.

No point in doing the stroker if you can't afford the heads. So I say build the 429 and get the heads. BTW, if you do go stroker, I'd probably go ahead and get the cylinders bored .030 giving you a 521. It's stupid easy to build 385's to 400+hp...and with a good set of heads, it'll be even easier. So forget the rotating assembly for now, and focus on the top end.

Your best money can be spent on the bottom, get the rotating assembly, (crank,pistons, rods,flywheel and dampner )ballanced. Once this is done, you can do whatever you want in the future to build HP and never have to rebuild the bottom. My 429 was stock for the most part but it was all proffessionaly ballanced, and with only a few other mild changes and a decent cam made 350hp with cast heads but turned 6500rpm with out floating the valves. If you start on the top end you can only go so far before you need to tear the bottom apart. What the factory calls ballanced and what a race shop calls ballanced is night and day, and the performance difference is incredible.

really, well i've heard from people that whats the point of having a 514 if it can breath and blow the exhaust out very well, so many people have said go with the heads, i've done some research and they say the 429 came with like 365 ish hp back in the day so i figure with an aggresive cam and heads, good exhaust, good intake and carb setup, roller rockers, some electric fans an some other **** that hopefully 400+ would be attainable. correct me if i'm wrong

400 horsepower is stupid easy with a 429/460. Edelbrock RPM, Offy POS, or something along the lines of a single plane with a cam with 235+ degrees @ .050 with headers and free flow exhaust.
As for heads, stock is good with a decent port, or pony up for some CJ or some nice Kaase heads. With the latter you'll be looking at nearly 500 with a cam of 250+ @ .050.
For streetability go with a 750 carb, for power you'll need 850+ CFM.

If I am spending your money I would go with a set of aftermarket heads. The engineering behind them will almost always trump the original heads.
And consider, whether it's Edelbrocks ($1500) or SVT CJ heads ($1700), they are ready to go, even if you have to swap springs to match your cam. With used heads you still need machine work, valves, hardware, porting etc, so in the end the cost difference ends up being very little.
Of course TFS, AFR or Kaase command bigger bucks.

Good luck finding forged 429 pistons. I had a set on back order for 6 mo. Speed pro moved oversees and don't make them anymore. My engine builder can have them made but are $100 each. Just get a pre 79 460 crankshaft or go ahead and stroke it. If I didn't already have the eagle rods I would stroke mine out.
