Overview
Swapping the camshaft in a fuel injected Ford small block starts with a kit like this one, which pairs an Xtreme Energy roller cam with upgraded roller lifters that use needle bearings. It is listed for factory roller blocks.
The cam targets a rougher idle and a strong top end while staying compatible with mass-air or aftermarket EFI, and it still leaves enough vacuum for power brakes. The caution is that the title and description give different end years, and nothing mentions a timing set.
Who it's for
Weekend street and strip builders with taller gears and a higher stall converter get the cam as intended. Daily drivers who want a smooth idle should pick something milder.
Pros and cons
- Roller cam with matched lifters
- Aggressive choppy idle
- Works with mass-air and aftermarket EFI
- Leaves vacuum for power brakes
- Model years given two ways
- Rough idle not for every driver
- Timing set not mentioned
- Needs taller gears per description
Performance notes
Lobe shape, duration and lift set how quickly and how far the valves open, so this profile shifts power to the mid and upper range. The lobe separation angle creates the rough idle, and the roller lifters follow the aggressive ramps using needle bearings.
