I am looking at a 70 lincoln w a 460 in it. What should I look for in terms of head codes and all that?
I am going to be sticking it in an amatuer bogger but wouldn't mind putting some cash/ parts in it over next winter. (don't tell the ol' lady!!!)

In my van I had a 73 lincoln 460 - the last year of the 365 hp 460's I was told and just did a valve seat job and put an rv grind cam in and beat that thing all over the US interstate system for four years and it is still boggin w the best of them.

Anyways... are there desireable heads on an ol' lincoln like that?
At least no smog bs and air ports etc.

the 70 should have the D0VE heads and D0VE block. both good starting points. the head casting number is right above the center exhaust ports, the block number is above the starter. most D0VE blocks had the thicker webs as they were also used in the CJ engines with 4 bolt mains.

only downside is that they have 10.5:1 compression and even on todays premium, you get some detonation. also they more than likely do not have hardened seats so that can also be a concern.

acually 71 was the last year of the hi compression 460's as in 72 they went to the disastorious open chamber heads and 8:5:1 compression and then 73 went with the D3VE heads, 8:5 ratio, retarded timing chain, etc. hp was in the 200 - 240 range, but it was measured different than the early engines, so the hp drop is not as dramatic as the number might indicate.

the 70 460 is a very good find and great starting point.

good luck

Hey Mike, Thanks for the info. I am all "christmas morning" excited now. It was listed on e-Bay as a good running motor from a wrecked lincoln so it's hard to say. Could even be a different motor by now. And if it was a daily driver, who knows, with the compression and valve seat worries maybe someone has allready done a seat job and dished pistons. Could be 50 over too who knows.

It's only money ( he said... while the wife wasn't around ).

Thanks... I'll post some more when I know for sure.

 

I got a chance to look at that motor today and I see that the block has a D1VE or DIVE casting above the starter.
I am unable to find the casting number on the head tho. I see 5B10 on ds and 4C21 on pass side. There is a symbol of two c's with a p beside or two c's with a M above. A 32 (ds) or 36 (ps) on an ear that sticks out on the corner.

Any idea if it's an original '70 lincoln motor?

Big oval ports or more like round at both ends but longer.

 

Well, since the D1VE is for 1971 and your head dates are 1975 and 1974, I would pretty much doubt it.

 

Bear, thanks for the reply. Where can I find codes and specs, etc.?

I was hoping for dove code block, heads, etc. I see the intake has a D0VE code on it so, with your info, I am going to assume that the mill was blown at some time and replaced with whatever could be found.

Are these head codes any good as far as a build-up? Valve size? CC size? Portable?

 

The D1VE block was used 1971 thru 1978 in Passenger Cars, 1973 thru midyear 1979 in F100/350's and 1975 thru midyear 1979 in Econolines.

The 460 was no longer available in Passenger Cars after 1978.

Ford replaced the D1VE block in midyear 1979 with the D9TE block.

There is no serial number break or production date, because this was a running change.

btw: Is it a 460? The D1VE block was used for both 460's and 1971/73 429's.

 

Good info... I would have to look at the crank and/or take off the heads to measure stroke to determine if its 429/460.

Bear 45/70 said the head codes are from 74-75 and it makes me think if it's a 75 motor it would have had hardened valve seats anyway but if the combustion chambers are huge then I am back to just a run-of-the-mill 460.

So... what would the 429 give me? A little less torque and hp but better topend rpms?

 

Since one (or both) of the heads have been replaced...who knows what was there originally?

One head was cast March 21, 1974 (4C21), the other February 10, 1975 (5B10).

The engine didn't come like that originally from the factory with a span of nearly 11 months separating the two heads.

Bore & Stroke: 429 = 4.36" x 3.59" // 460 = 4.36" x 3.85"

 

with the casting # not on the exhaust side of the head its most likely a D3 head. A lot of them did not have the casting number there.
the 1975 production year code also supports that they'd be D3's

 

What is the exact block casting number? There are three possibilities.

D1VE-6015-AB = 1971/72 / D1VE-6015-AB1 - D1VE-6015-AB2 = 1973/midyear 1979.

 

If you pull the oil pan, look for a flat place on the counterweight on the crank & should be a number & letter stamped on it. 2Y or 3Y would be 460 & 4U a 429.

little husky, I hateto be too stupid, but what is a D3 head? Are they any good or just early smog heads? I don't see any air injection ports or anything unusual.
