429 info

Hey.
Could somebody that knows any information about the 429 such as hp & torque numbers, the best year, and any opinions on which is better 429 or 460 or any other news, give it to me. Any input is appreciated.
Later.

Re: 429 info

As you probably know the 429 and 460 are made from the same block, except for the BOSS 429, which was a quasi-hemi built to do battle with Mopar's hemi.

The 429s haven't been put into passenger vehicles in a long, long time. I'm pretty sure it was replaced with the 460 in the early to mid seventies. Any servicable 429 you find will require at least a freshening up, if not an entire rebuild at that age. So all things being equal, go for the extra cubic inch advantage of the 460.

Another consideration is that the earlier 429s were high compression and non hardened valve seats and therefore require new seats, valves and probably pistons, stick with the 460.

My advice

Didn't the older engines have thicker webs, so it made them stronger?

Re: 429 info

A 460 is a stroked 429. The seats were hardened when fuel went from leaded to unleaded to prevent heat scuffing. There were different tweakings to the 429, including adding extra webbing in the block for strength.
I know I'll probably get grief for saying this, but the Boss 429 was a disappointment. Slower than a Boss 302 and a 428CJ.
You obviously have a woody for a 429, send me an email, and I can give you some basic info.

The 1993 F-700 Dump and 1995 F-750 Dump trucks that i drive for work both have 429's in them...i found a spec sheet for the older one behind the seat one day...it was making ~230 horse and ~350ft-lbs, but at some really low rpm's....the motor's got power though....i can start it in third with the axle in high and 8 yards of rock salt in the back.....
