D0VE heads Q & other misc. opinions wanted

Hey guys, I'm new to the site, but not to the great Ford 385 series engine. I've had a 1972 Lincoln Mark IV with the 460 since I was 15. While it's a heavy car, and I don't expect to tear up the track anytime soon, I still want to get a little more power out of it. I've already upgraded to a performance electronic ignition (Pertronix Ignitor II) and high performance coil (Pertronix Flamethrower II), but recently I came across a complete 460 engine from a 69 Continental Mark III. My 72 has the lower compression heads (8.5:1), whereas the 69 has 10.5:1 compression. Technically, aren't the 69 heads C9VE vs. D0VE (which would be the 1970 model heads)? If so, are there any differences in the C9VE and D0VE heads? I know the compression ratios from 1969 to 1971 were the same. The reason I'm asking this is I'm wanting to swap heads from the 69 engine to my 72, along with picking up a pre-72 timing chain to boost the power. I've seen people slap D0VE heads on later model Marks with the 460 with no other modifications, so I'm hoping this will work in my application. Obviously, I know I'm going to have to run premium fuel at all times if I do this. What I'm planning on doing at this point is picking up the 69 engine, using the heads on my 72, and building the block for another project.

Also, this same seller has a 460 block with rotating assembly, bored .60 over with a stroker kit (he didn't specify, but I'm assuming it's the 514 crank). He wants $800 for that setup, which doesn't sound like a bad deal to me, but I was told with such a large bore, the engine would be good for little more than 1/4 mile runs at the strip because it would overheat (I'm wanting to build a street/strip vehicle). I know that my 72, basically stock 460 is a hot-natured engine, so I was just curious what you guys thought about this. Would it be prone to overheat to the point it wouldn't be a practical street engine, and is $800 a good deal on something like this? It sounds like a good deal to me, but I know you guys are probably more aware of the big block market than I am.

Any and all replies are welcome. Thanks.

hi,
the c9 and d0 heads are the same, as are the c8.
the d0ve's arent as detonation prone as the d2ve's that would be stock in your engine.
the stroker engine even at .060 over shouldnt have that much for overheating issues unless your cooling system is marginal to begin with.

If so, are there any differences in the C9VE and D0VE heads?C9VE and D0VE heads are the same except that D0VEs may or may not be drilled with smog pump passages. When swapping out D2VEs (<---1972 heads) for C9VEs/D0VEs, the valve trains are different between the D2VE's and the C9VE/D0VE's. You will need to transfer the entire valve train (pushrods on up) with the cylinder head swap.

Also, this same seller has a 460 block with rotating assembly, bored .60 over with a stroker kit...I was told with such a large bore, the engine would be good for little more than 1/4 mile runs at the strip because it would overheat...That is not true. This misdirected belief that "thin cylinders cause overheating" originates with the Flat Head Ford engine which has the exhaust ports running through the block and around the cylinders and then exiting out through the cylinder banks of the block. When the Ford Flat head's cylinders were bored too thin, the super hot exhaust gases that surround the outside of the bores would allow for the cylinders to get way too hot (combustion inside + exhaust gases outside). Your 429/460 block is fully water jacketed around the cylinders and the water takes away heat. It does not add heat....trust me, the water is much cooler than the inside of the 460 cylinders of a running engine. ;)

The earlier heads ran leaded fuel a hardened seat and valvejob would probably be a good idea . What is the history of the stroker is it a used race engine or fresh rebuild ? If possible I would have the bore taper checked on it , I got burned on a .060 over 460 once thought could still go to .080 but when I took it to machine shop it had .065 taper making it useless . I paid 150 for short block and only useable part was the crank after a 10/10 cut :mad:

I would agree with Paul on the overheating advice, unless the block has been "filled" for strength... if this was done, what the seller told you may very well be true. It would be best to ask if the block has been filled.
