Selecting Parts
Choosing the right engine castings and parts for your application isn’t as simple as it sounds.
Ford's peppy small-block has been through untold changes since it was introduced in 1962 as the
90-degree Fairlane V-8. Although Ford buffs love to curse Father Ford, running changes are
commonplace at Ford because Dearborn never remains very content with things as they are. As a
result, the small-block Ford has been ever changing for more than 40 years.
289 block with 6 bolt bellhousing
This is the large six-bolt
bellhousing bolt pattern from
1965 to present. As you might
imagine, this is a more common
and logical replacement for that
1962 to 64 five-bolt block if you’
re not concerned about
originality. With this six-bolt
pattern, you open yourself up to
a wider variety of transmissions
and bellhousings.
Though there have been many changes in the small-block Ford over the years, the changes are
simple to understand. In its original form, the 221/260/289-ci small-block had a five-bolt (narrow
pattern) bellhousing pattern. We find this pattern from 1962 to ’64 only. From 1965 and up, there is
a six-bolt bellhousing pattern, which is the most common. This means a late-model 5.0L engine will
bolt right up to a 1965 and up C4, T-10, or Top Loader transmission (wide pattern) bellhousing. It
also means a 1965 and up 289/302-ci small-block will bolt right up to a late-model Automatic
Overdrive or T-5 5-speed. Engine mount attachment points have never changed, which makes
these swaps simple in scope.

Ford went from the five-bolt to the six-bolt bellhousing pattern in 1965 for one simple reason: By
expanding the pattern and adding the sixth bolt, vibration and noise are distributed over a broader
area, which reduced noise, vibration, and harshness. Ford did the same thing with the 170- and
200-ci sixes to quiet things down. If you’re trying to improve your vintage Ford without concern for
originality, ditch the five-bolt block and related transmission, and opt for a six-bolt duo. This will
make things easier on you because the parts are much more common
The 221- and 260-ci blocks differed from the 289/302 blocks in bore size. Neither block had a
4-inch bore, but instead they had 3.50- and 3.80-inch bores, respectively. They also employ
7/16-inch bellhousing bolts instead of 1/2-inch like we find in the 289/302 blocks. The 289 was the
first small-block Ford to have a 4.000-inch bore. And because the 302 also has a 4.000-inch bore,
it has basically the same block as the 289. When Ford first began casting 302 blocks in mid 1967
(as 1968 castings), they had slightly longer cylinder skirts to give the piston greater stability at the
bottom of the bore.  We have documented 302 blocks in 1967 Fords with 289 internals. This proves
that the Ford factory built 1967-vintage 289s using 302 blocks. We are convinced this practice
continued through 1968.
5.0L Roller Tappet Engine Block 5.0L Block with Studs Retaining the Main Caps
This is the late-model, 5.0L roller-tappet
block, an excellent foundation for any
small-block Ford project. It has provisions
for the roller tappets, a one-piece rear-main
seal, and is designed for the serpentine belt
drive in front.
Here’s what you can do with a small-block
Ford. Look at these five main bearings with
studs. This makes the foundation nice and
rigid – good for high-revving bottom ends.
Although a lot of different six-bolt block casting numbers have appeared since 1965, not much
has changed through the years. From 1965-84, 289/302 blocks were virtually the same except
for the cast-in front accessory drive mount on the right-hand side, which first appeared with
the introduction of serpentine belt drive. Another significant change was the one-piece rear
main seal, which first appeared for 1985. Crankshafts are not interchangeable at this point.
Crankshafts with the lip for a two-piece seal will not work in the one-piece seal block. By the
same token, the lipless one-piece seal crank will not work in a two-piece seal block because it
will leak. The lip works hand in hand with the two-piece seal. Without the lip, it’s a leaker.
Installing the crankshaft in the 5.0L Engine Block
John DaLuz of JMC
Motorsports in San Diego,
California, understands the
importance of selecting the
right parts for an engine build.
John’s first question for a
customer is “how do you
intend to drive the car?”
Before you order parts, you
must know how you intend to
use the engine.
351W engine block
This is the 351W block, which
is based on the 289/302
block. Where this block
differs is its taller deck (1.274
inches taller), which allows for
a 1/2-inch longer stroke. This
deck height difference makes
the 351W wider than the
Two types of small-block castings had wider main bearing caps – the 289 High Performance block
and all Mexican-block 289s and 302s. Contrary to what we have all been told through the years, it
turns out Mexican blocks are not made of high-nickel iron. They weigh virtually the same as their

U.S. counterparts. The only benefit is the wider main caps we find south of the border.
