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.
I like the 429. You can still find them around in the early 70's sleds and are easy to pump up. I would find a 68-71 429 because the compression ratio was up to 10.5 for the 2v and 11.0 for the 4v. The comb chamber was 75.8cc vs 91.4 for the 72. With a slightly dished piston, you can have a very streetable 9.5:1 motor. If you go with a cam much larger than stock, I would put better springs, roller rockers, hardened pushrods and guideplates in it.
I guess it depends on what you're going to use the motor for. Towing or racing around. You can improve the 460 with a set of cobra-jet heads too.
I have to be different. I prefer the 460. You know the saying, "No Replacement For Displacement." Really it would depend on what you are going to be doing with the motor. Towing or hauling, the added torque of a 460 would be your best bet. Racing would be the 429 because you can rev a shorter stroked motor higher than a longer one. If you just want and everyday driver that is dependable, stick with what you have.....If you have a 429 stay with it, if you have a 460 stay with it. Hope that helps.

OK heres my 2 cents, The difference between the 429 & 460 is the crank and pistons, and from what I understand that is it. Now having said that I aggree with Heetseeker in saying to stay with the 68 - 71 year model because it is a higher compression motor, and also T Bird is right too cubic inch IS HP. It does depend on what you plan to do with it,towing or crusing town lookin for camaro's to feed on. I have a 68 model 429 that is at the machine shop now getting punched .30 over and balanced with a 501 stroker kit, it will be a street truck, but you can do the same with a 460, the main thing is to match your parts and dont just go out and buy a lot of "high performance stuff" and stick it all together and hope is is what you wanted. Now I won't be towing with mine, so all I'm hoping for is to pass at least every other gas station.
