Best bang for the buck..

Through displacement at it. A 514 to 572 stroker kit and it'll be fun than shooting fish in a barrel. Some SCJ, P51, or blue thunder aluminum heads and a 750hp streetable combination wouldnt be out of the question depending on cam.

Heck yeah!

I have a 429 in a 67 Fastback. Sounds like we'll have simular cars.

I have Crites performance motor mounts and trans cross member. No shock tower mods. Plugs take about an hour to change, other than that. Pretty easy to work on.

My current set up, is .030 over with old (built this 20 years ago) TRW flat tops, very mildly ported C8 heads with a, if memory is correct, 272H comp flat tappet hydrolic cam. Police manifolds, 2.5 exhaust out the back threw 2 chamber flow masters. Stock converter with a mild C6. 3.55 gears, car weights 4200 with me in it. Went 11.92 best with street tires on it, way back then.  Pretty mellow, solid street car. Durable to no end lol

Hope that helps ya some.

shoot yeah that helps a lot!!! ive been wondering how its gonna act with that big block in it... i plan on swappng in a mustang 2 front end to eliminate the shock towers and give it a little more room....i read something about using the rotating assembly out of a 460 to mildly stroke the 429....know what all that would consist of?

Crank and rods, piston are the same 429/460 I believe. I am rusty on my 385 family interchanges. There are plenty of gurus here. And a few threads I am sure if you search.

All you need is a 460 crank, rods are the same for 429-460. Make sure you get an early internally balanced crank to go with the parts you have. Have fun.

I forgot to mention that 429 pistons are not the same as 460 pistons. If you go to a 460 crank you will need 460 pistons. An added benefit is that there are a lot more pistons available for the 460 than the 429. Good luck.

ok now im confused..... i knew the 460 pistons would be bigger and couldnt be used in a 429 block without boring ..... but if the rods are the same then can i just change the crank and use the 429 rods and pistons with the 460 crank? Am i missing something?

The 429 crank is a shorter through, or stroke. The rods are the same. Ford used a weird piston with the 429 with a very low pin height.

To put a 460 crank in a 429 block, you can use the 460 crank, the rods are the same, and 460 pistons. The bore is the same.


370
Bore: 4.050"
Stroke: 3.59"

429
Bore: 4.360"
Stroke: 3.59"
Chamber size (C8VE/C9VE/D0VE): ~72-75cc

460
Bore: 4.360"
Stroke: 3.85"
Chamber size (C8VE/C9VE/D0VE) 75cc
Chamber size (D2VE) ~99-100cc
Chamber size (D3VE/E6TE): ~93-95cc

Pistons are not the same, only part that's the same is the rods at 6.605

460 used a 3.85 stroke crank and a 429 uses a 3.59.... But they both share the same journal sizes.

And just for in info internal balanced factory cranks will not fit in the late model D9 blocks, but the later external balance cranks will fit in the early blocks

Piston compression height for stock 429 pistons is 1.89 for stock 460 1.76. Hope this helps.
