429 Help to 1967 mustang!!!!!!!!!

Dimensions on the engine bay of the 67-70 are nearly identical, they ARE identical in most ways. A normal headed 385/Lima motor (not a 429-boss) WILL fit without sheetmetal work, your only gonna need swap parts, start with mounts and exhaust, the rest is even easier.
67GTA, that is backward WRT the block, the 385 series were designed much like the Windsors, the bottom of the block was the centerline of the crank, it did not have "Y" shape from the longer "skirts" of the FE series.

OH. Ok. (now I feel old)
So you are saying that the 385s have a shorter deck height than the FEs?
HH: The exhaust manifolds are a great choice. That is what I have on my car and I am just under 400hp at the wheels. They are a cheaper and easier exhaust solution as opposed to $700 'special' headers.

I do too, all the time, I'm just used to the "l337 $pe4K o teh intardnet", also known as typing for the lazy
Not authoritative enough on that, I don't even know the relative deck heights but the block itself is generaly a larger verion of the windsor (260/289/302/351) style of compactness, whereas the FE was a new version of the "Y". I was trying to find good illustrations of this on the web but got tired of looking and I can't draw it in ASCI so let me try words...67GTA-FB429 said:
The lower portion of the block on the FE series used the heavy cast iron skirts that came straight down from the cylinder walls to the pan rails PAST the centerline of the crank. This gave them great strength (also allowed for cross-bolting the main caps) but also great weight. The 385s (and 335s) used the more modern (at that time) method of "thin walled casting" and stopping the block at the centerline of the crank just like on the Windsors. A Lima-460 block wieghs less than a 360-FE, and has the advantages of canted valve heads (but the heads are larger/heavier) but total engine weight is in the ballpark.
Somewhat ironic is that the truly modern engines (4.6/5.4 SOHC/DOHC) have gone back to a long skirt design and although they have small displacement they are larger than a 429 Boss!
I can't find an exact weight of the 428 FE vs. 429/460 weight because they all vary from source to source. This point comes up every now and then. I was always under the impression that the 429/460 was heavier though it was intended to be lighter than the 428. When you are getting into the heavy weight class of engines... I doubt it will matter much either way... Should be a nonissue.
