Rebuild Cost?
What will it cost to get a 71' 429 rebuilt with a better cam, new seals, bearings, and a possible overbore? BTW, i am getting the motor from a friend that used in his truck but he blew it up. And also it already has intak, carb, and a set of headers and a 3000 stal convertor on the tranny.
P.S. Is there any difference between the car 429's and the truck 429s of that year? Thanks for any help.

No difference in car and light truck 429s. Some truck 460s had better rods.
Costs will vary depending on your locale and how much of the work you do yourself. You can price all the required components once you get the engine torn down and see what's needed.

Iam in the process of rebuilding a 1989 460 truck engine. It is a little more expensive than the 70's vintage big blocks because of the gaskets. Mine $725 parts $275 machine work. This is complete new pistons, all bearings, crane cam, lifters, soft plugs new valve springs, oil pump, full set of gaskets, timimg gear and chain. Machine work is turn crank, bore block vat and install new cam bearings magnflux heads, surface heads, valve job and install pistons on rods.
These big blocks are not cheap to work on.

You wont know how much its gonna cost until you know whats wrong with it. "My friend blew it up" is a pretty general term. If he cracked the crank or anything more serious than just say spun a bearing you could be into some cash.

The shop I talked to wants that just to clean & bore the block and replace the cam bearings. Heads are another 3-400 just for refacing.
Where is this shop you go to?

RoundLights is right. Before you take it a shop, or even talk to them, tear it apart yourself and find out what's wrong with it. If you take it to a shop and tell them to rebuild it, you're just saying "I'm stupid and my checkbook is open. Take advantage of me!"
If you've never torn down a 460, they are like any other Ford V8 -- very simple...just large by wide. No tricks. No special tools. And no tiny weird pieces to drive you nuts when it comes reassembly time.
Invest $12 in a copy of the Haynes "Ford Engine Overhaul Manual". You can get it at or through any CheckZoneBoyz as Haynes Manual #1763. It will walk you through each step of the process.
There are too many good older 460's out there to waste your time on one that's been "blown up". IMO, if there is much more damage than a spun bearing or blown headgasket, you'll be better off to get a rebuilder from a salvage yard for a couple hundred bucks.
Good luck!

Oops! I just realized that you said a 429, not 460.
If this is the engine you want, and the 429 is a fine engine, then I'd be prepared to pay a little more to recover the crank. FWIW, only the crankshaft needs to be salvaged from this engine, as good used parts (not the rebuild kit) from a 460 will substitute for everything else just fine.
There were differences between the truck 429 and the hi-po 429, but not between it and run of the mill car 429's.
Edit: The only difference between a 429 and a 460 rebuild kit for a given year is the pistons. The 429 pistons have a higher compression height than the 460 slugs, and are not interchangable with the 460. The 68-71 429 kit has a better timing chain - if you can use it, you may wish to buy this kit.

I now know that the motor was overheated (water pump) and the guy (neighbor and good friend) says that he thinks its not hurt that bad. We will be doing a complete rebuild witch will include a hotter cam, possible head job, overbore, 460 crank and all the goodies to go with it, a port match and an ARP bottom end. Now we can do everything but the headwork, overbore, and cam bearings. And me and my dad will assemble and disassemble the motor (will only need a book to make sure we get the torque specs right) with the machine shop (other then stated above) making sure that the block and heads are in tip top shape.
Now i have several extra 429s and 460s in a shed and if the block is bad on the 429 we'll be getting i will look for the best one of the extras(are any year or block better then the next?)
If you haven't already noticed i am looking for a little bit more performance.

I just looked up machine shop costs for my last rebuild:
Hot tank bake - 50.00
Bore .030 with torque plate, hone for rings - 95.00
Cam bearings (included install) - 28.00
Deck block, line bore mains - 153.00
Turn crank 10/10 75.00
Rods aligned and hung on pistons - 57.00
Balance rotating assembly - 175.00
Block magged & sonic checked - 125.00
$758.00
Other than the cam bearings and cylinder honing, there's nothing there I could do myself without a machine shop at my disposal and someone instructing me on how to perform each operation.
And that's no head work.

So, since i am in Canada that price is gonna be in the 1000-1100 dollar range (maybe cheaper cause the machine shop here is really good and they don't charge muchand i might not need to do everything that you have done) and a head job will most likely cost in the $300 range. I guess that i will have more than enough money for a build even with the cost of parts. Thanks guys.
