What is the lifter diameter of a Ford FE engine?

The standard FE lifter diameter is the same as other Ford engines at.874 inch, but I have gone to.904- inch diameters in serious race applications. Larger-diameter lifters offer advantages in terms of strength, and on flat-tappet cams they allow more aggressive lobe profiles.

How can you tell if a Ford FE engine is a 427?

The block is bulged out to accommodate this oil passage, and there are pipe plugs in this bulge, so a sideoiler is easily identified. Unfortunately, the vast majority of FE engines are not 427s, so in most cases the bore and stroke must be measured to determine what you’ve got.

What kind of cam bearings do I need for a FE engine?

Cam bearings for FE engines are babbit lined and are manufactured by either Durabond or Federal- Mogul. Standard center-oiler FE blocks all use the same cam bearing set. The inside diameters are identical, but outside diameters get smaller as you go farther back into the block.

How big of a bore does a Ford FE engine have?

With some 390 blocks (4.05” bore) you can get away with boring them to 4.13”, which is the 428 bore size, but again you need to exercise caution when doing this. FE blocks often exhibit core shift which makes boring to large sizes very dangerous.

Which is larger a.904 or.842 lifter bore?

A nominal .904″ lifter bore has a circumference of 2.83992″ versus an .842″s 2.64514″. Thus, a .0015″ diameter clearance, or .00472″ circumference, is a greater percentage of the smaller diameter. Just as a function of diameter, the .904″ is 7.36% greater diameter/circumference.

Can you use roller cam bearings on a 460 engine?

Roller cam bearings have been occasionally used in Super Stock level engine builds. The aftermarket blocks have additional material in the cam tunnel, making installation easier. The parts designed for 460-style engines can be made to work.
