Hydraulic Roller Cams Hydraulic Roller Cam Motor

All Ford hydraulic roller cam motors use a net valve lash system for the rocker arms. When moving up to a performance roller cam, you should spend the money to have the stock heads machined for screw-in studs and guideplates so you can use an adjustable valvetrain and roller rockers. These stock iron heads now sport Crane 31/48-inch screw-in studs, guideplates, hardened pushrods, and Energizer 1.6:1 roller rockers. Slover's Porting Service did the work for us on these heads.

Ford Firing Order
If you are considering swapping in a hydraulic roller cam into an earlier block, be sure to pay attention to the firing order. Early small-block 289/302 Fords used the 1-5-4-2-6-3-7-8 firing order. But when Ford converted to the 5.0L roller cam engines, it changed the firing order to the 351W sequence 1-3-7-2-6-5-4-8. Just to make it really confusing, the same-era fullsize Fords without roller cams retain the older 289/302 firing order. When purchasing an aftermarket hydraulic roller camshaft, be sure you know which firing order the cam is ground with. Most aftermarket hydraulic roller cams are produced with the 5.0L/351W firing order. Also worth noting is that Ford numbers its cylinders 1 through 4 front to rear on the passenger side with 5 through 8 on the driver side.

What is a RetroFit?
Because both the small-block Ford and small-block Chevy engines came in both flat-tappet and hydraulic roller versions, this does cause some confusion for parts buyers. To convert an early flat-tappet engine to a roller cam requires what the cam companies call a retrofit kit. These early engines cannot utilize the factory-style hydraulic roller lifters and retainer design. Unfortunately, this means that the cam packages and especially the lifters are more expensive. So if there is a 355 or 383 small-block Chevy or a 5.0L Ford in your future, you should consider going with a factory-style hydraulic roller cam and lifter setup. OE-style replacement hydraulic roller lifters are much less expensive, and as long as you're not spinning over 6,500 rpm, this would be a great combination as opposed to the more expensive retrofit roller cam kits.
