429 crank shaft

Post  motorhead on February 19th 2012, 9:11 pm

I'm a new member and a ford motorhead for life. I bought a 429 last week and as
i was inspecting the crank, I noticed the different stampings on the counter weights. The 7th counter had ($D) stamped on it and I was researching the markings but have not had any luck. This is a ford crank shaft and (H98) is on the 8th counter weight. Any help on this would be appreciated.

429 crank shaft

Sorry it took so long to get back but I just got home from a 12 hour work day. I can't find 4U on the crank but I did find D9TE on it along with H98 and F71514. I was just wandering why Ford stamped a $ dollar sign on the 7th counter. The motor came out of a Fire Department truck that was headed for the crusher last Thursday.

Well, you saved a neat piece. Those 429 big truck cranks are forged, and that is what you have. Google "429 truck crank" and do some reading. They are valuable to the right person.

Thanks for the info. I'm new to the 385 world as my other motor is an FE and I remember the forged FE cranks had the $ mark on them. This motor only had 21K on it and has never been bored but I'm sure it had a lot of idle time. I'm taking it to the machine shop this week for a short block build and I will put P51s on top. The rest of the build will be as wild as I can get away with on the street.

You are going to run into some issues. That crank has a snout that is different than standard BBF stuff. The pilot area on the back of the crank is different as well. Like I said, google "429 truck crank" and do some reading. I'm sure Paul Kane will chime in here eventually, but you could contact him @ highflowdynamics.com for some information. He is the resident expert on factory available BBF forged cranks. I'll post some links in a minute.

I apologize for them being from the other site, but most of the info on them is over there. Like I said, they are neat, but there are really only a handful of scenarios in which you would want to run one.

429 crank

Post  motorhead on February 21st 2012, 8:10 pm

Well I just got home and I realize I might not be able to use the motor I bought last week. Thanks Jared for the information on the crank and if there is a way to use it for my build I will, but if not then maybe I can find a buyer for the crank. I have a 77 F-150 4x4 with a 6" lift on 38 Swampers powered buy a 351M. I am going to install this 429 if I can but if not, then I will get another one. I also have a 67 truck with a 390 and a 73 with a 302, so I decided to keep things interesting and join in with the 385 crowd. I have a lot to learn and learning from mistakes is a lasting indeavor. Any more information will be much appreciated and I am checking out the other links you left me. Thanks again.

Slap a 460 crank in that thing and enjoy the extra cubes. Very Happy

Glad to help. Factory BBF cast cranks are unbelievably strong, so it really isn't worth spending the money to rework the HD429 crank unless your build is appropriate for it. The guys that search out the HD429 cranks are generally truck pullers that are limited to less than 500 cubic inches. There are other reasons to want to use one of those too of course. Nobody offers a forging in the stock stroke range, so a billet or a reworked HD429 crank are the only option if you need a sub 4" stroke forged crank.

The rest of that motor is entirely usable for building a "normal" 460 based engine. The front cover and the timing chain excluded. I'd be interested in the crank or the whole motor if you were in my neighborhood. I have plenty of other 460's you might be interested in as well.

429 crank

Post  motorhead on February 21st 2012, 8:59 pm

Could I use the block as is with the oem timing chain as long as I address the pilot bushing issue.I have all of the pulleys and brackets along with the damper which appears to be in good shape. I have no intentions on using the heads or intake. If I did get a 460 crank could I use the HD rods?

You absolutely could use front cover, timing set, and dampener that you have. The HD rods are unique to the HD engine, and are not compatible with typical performance pistons as far as I know. You could always crunch some numbers and maybe find a piston that would work, but it's not really worth the effort. They are shorter than normal 6.605" BBF rods. If you really want to use that crank in a street type build, have it offset ground to 3.85" using the 2.200" BBC rod journal. You could then select from any number of affordable 6.800" BBC connecting rods, and utilize the ICON forged piston for that exact application. It will end up being an expensive stock stroke 460, but it will have a forged crank. The other option is to just use a standard 6.605" BBF rod and a shelf 429 passenger car type piston, netting you a more conventional 429. There aren't many options there though either.

A good read on the strength of the stock cast cranks.

I'd put that crank on the shelf for something else if it were mine. Get a good 460 rotator and enjoy the extra cubes. There are many affordable stroker kits that would suit that block nicely as well.

I have a few of those cranks too, as well as a few cast units. The nicest HD crank I have was also from a fire truck. It had only 15k miles, and was mint.

Well I don't know where your located but I'm in North Carolina and if you wanted to buy this engine or do some trading I guess distance would be the issue because all I want is a regular motor to build on, but I've got what I've got.

If you have to buy a Crank Rods and Pistons anyway, just look into a stroker kit and build a 521 or 545.

Sell the Steel Crank to recoup some of the $$$ towards the Stroker build.
