The first step is to ID the engine block. The block casting number is found at the rear of the Cadillac engine, between the intake manifold and transmission bell housing, right next to the oil pressure sending unit. The casting number is the raised, cast in number on the passenger side. Note that the ’68-’69 (and a few rare ’70 472s) use a block th...
The ’68-’70 472″ and ’70 500″ engines have the 10:1 (or 10.5:1) pistons. Do not assume your high lift cam will work with those pistons! Those are compression reliefs, not valve reliefs. The Dish is shaped something like a figure 8 or ‘squashed peanut’, and is sometimes described as 2 overlapping round dishes. The ’68/’69 dish is a slightly differen...
500 crank casting numbers are usually next to the 2nd or 4th main journal. 472s are usually on the 3rd counterweight. The 425 and 368 crank is the same stroke as the 472 crank, and is physically interchangeable, but this is not recommended due to balancing and weakness issues. The 425 and 368 crankshafts can usually be identified by a scalloped sha...
The cylinder head casting numbers can be found in 3 places. The full 7 digit casting number can be found on the top of the head, between the rocker mounting points. It is not uncommon for this number to be missing. The last 3 digits of the casting number can always be found on the bottom side of the head, in a recess under one fo the center exhaust...
’68 – mid ’70 engines used the first generation heat operated choke, with an exhaust passage around the front of the carb. These intakes have a cast rectangular box-shaped choke well. Mid’70-’73 engines do not have the heat passage around the carb, and have a round choke well with what looks like a freeze plug in the bottom of it. Many ’68-’70 engi...

- Cadillac L-Head V8. The Cadillac L-Head was the first mass-produced V8 engine available in the world, leap-frogging over the handful of experimental eight-cylinders that had trickled out of shops in Europe over the previous decade.
- Cadillac 331 Series V8. In 1949, Cadillac borrowed a page from corporate cousin Buick's book and introduced its own overhead valve V8 engine. Dubbed the '331 Series' after its initial displacement (in cubic inches), the engine generated 160 hp and 312 lb-ft of torque, numbers that climbed to 270 hp just six years later.
- Cadillac 472 Series V8. The largest big block V8 ever produced by Cadillac was the 500 cubic inch edition of the 472 series. The 472 series arrived in 1968 and was good for a whopping 375 hp and 525 lb-ft of torque, but just two years later Cadillac increased displacement to a mammoth 500 cubes, giving it 400 hp and 550 lb-ft of twist in the front-wheel drive Eldorado coupe and convertible.
- Cadillac Northstar V8. The 1993 Northstar V8 was the first all-aluminum effort from the brand, and it brought with it many modern advancements that had been lacking throughout the previous decade.
