429 or 460

I have a 1976 Cobra II with a 429, not sure if I should keep it a 429 or make it a 460, any ideas?

cool Re: 429 or 460

Depends on the application and what you want to do.

If you have a fine running engine/car, you might not want to mess with it until necessary...or maybe begin building another engine on the side.

Re: 429 or 460

I have bad bearings, so its a rebuild. got two different answers from different machine shops. Thought I would ask to see what kind suggestions others had. I have a c-4 trans, 4-11 9 inch spool, 4000 jpt stall converter, motor plate, alum rad, 15 in bfgs in rear 13s in front, trans cooler,750 holley, looking for a stealth intake, looking for a 550 or so cam, looking for alum heads. Putting in new pistons and rods, just dont want to get to crazy w/bb done that with sm block,not so fun.

C-4? Did you mean C6? I would consider upgrading to a C6 before an egine upgrade.

Well in that case, the only difference between a 429 and a 460 is the crankshaft and pistons, and your already getting new pistons. So installing a 460 crankshaft is an easy 31 cubic inch "stroker" upgrade along with the new 460 pistons.

550 hp from a 460 is not that difficult. And it can be done with factory iron heads, although the aluminum has its advantages.

Does this car have to pass emissions tests? Drag car only or street/strip? Pump gas only or race gas? Compression ratio that you desire?

Re: 429 or 460

between the two i prefer the 460. it revs better than the 429 does, has about the same rpm limit, and the fuel economy is the same, and sometimes better with the 460.

Re: 429 or 460

It took a while to squeeze ( A large shoehorn LOL) it in there, decided to go with a 460 crank. As soon as I can get the motor in I'll get some pictures on the site.

Stock for stock yes,but he's not stock. With the same intake,compression,ect.the 460 will make more power. No replacement for displacement.
