If I remember right, the V12 is 292 cu. in. It's easy to take a V8 out to 296 cu. in. So which one will perform better, given similar heads, carbs and cam?
 
Now all you need is an L-100 cam and your all set. Just remember a 60 deg V12 is the only engine configuration that can be balanced in all harmonics. Just think of them PackardMerlins V-12 in the Mustangs. Also Formula 1 3L Farraers engines put out over 400 hp for 24 Hrs at over 12,000 rpm and that was 40 years ago.
 
75 degree and mine is 267CI


Similar in design to the 90° Ford flathead V8 introduced for 1932, the Lincoln-Zephyr H Series V-12 had a narrower 75° between cylinder banks.The engine used aluminum-alloy heads and cast-steel pistons, as well as two water pumps. It also had a unique distributor with a coil assembly that actually consisted of two coils, one for each cylinder bank.

Initial power output was quoted as 110 horsepower -- a little higher than the target figure -- at 3,900 rpm, a rather high power peak for those days. The torque curve was quite flat, however, with at least 180 pounds/feet available from 3,500 rpm all the way down to 400 rpm, which made for incredible top-gear performance. Though the Zephyr V-12 no more resembled previous Lincoln engines than the ubiquitous V-8 (despite sharing the latter's stroke), it was more like a "12-cylinder Ford" than a classic multi-cylinder powerplant in character. And it was not without problems. The main ones were inadequate crankcase ventilation that caused rapid sludge buildup in sustained low-rpm running, aggravated by poor oil flow, plus too-small water passages that led to overheating, bore warpage, and ring wear. To a degree, some of these maladies were dealt with during the Zephyr's first year, and Ford improved the engine by adopting hydraulic valve lifters for 1938 and cast-iron heads and oiling improvements for 1942. Yet this V-12 never shed its reputation for service troubles, though the postwar versions were actually quite reliable.
The first Lincoln-Zephyr models of 1936 used a 267 cu. in. (4.4 L) engine which produced 110 hp (82 kW). This engine was upgraded with hydraulic lifters in 1938 and produced for one further year.

292[edit]
The engine was enlarged for 1940 and 1941 to 292 cu. in. (4.8 L). This engine was reused from late 1946 through 1948 and was the last of the line produced.

306[edit]
A single month of 1942 production used a 306 cu. in. (5.0 L) version of the engine. This was resurrected after the war in 1946 (with 7.2:1 compression and 2-barrel {twin choke} carburetor, rated at 130 hp {97 kW})[1] for a short time before reverting to 292 cu. in. for the rest of 1946 through 1948. The reason for the reversion to the smaller size was that the cylinder walls on the bored-out engine were found to be too thin. Many disappeared altogether in the block casting process at the factory causing many blocks to be scrapped before installation. Cylinder wear in the field was extreme, and re-boring during engine overhaul was impossible.

I believe the Ford flathead V8 will always out perform the Lincoln V12.
Because of the individual intake ports on the V8, vs the shared ports on the V12
 
I agree. The intake and exhaust ports of the V-12 are a significant impediment to flow and distribution.

I believe they are open plenum manifolds, as I don't think Ken Austin made the 180 degree type.
Not a problem as far as I'm concerned
