Yes, it is possible to put a 460 crank into a 429 Cobra Jet engine. All that is needed is 460 crankshaft and 460 pistons.

I think it's a great move to do this, as the HUGE intake ports of the D0OE-R head castings of the 429 CJ are a major mismatch for the 429 displacement and the 3.59 stroke of the 429 crank, unless you opereate this engine at 7500 rpm.

Installing the 460 crank & pistons will improve low end torque and the overall usable power range/output of the engine. Frankly, the CJ heads are designed in such a way that they really don't wake up these engines until about 500 cubic inches.

Stroker kits are typically $1000 give or take, and a stock crank and pistons aren't near that. If you can stroke your motor for another 31 cubes (429 to 460) for a few hundred bucks, then I say go for it. The increased usable power output will be very noticable.
