Cam Shaft billet Steel Roller 250 / 292 Chevy Inline 6
n/a
This steel billet mechanical solid roller Crane Cam shaft was built using the small base core to help clear large body 292 inline Chevy Six connecting rods.
The fuel pump eccentric was never used and is still there in the 292 center position. To use in a low deck 250 engine an electric fuel pump must be used. The distributor gear is perfect. Front is drilled and tapped for Cam gear retainer.
We have tested and used many Billet Steel Roller Cams smaller and larger than this one and we would not all consider this a good street able Cam Shaft at all. It is a competition type grind and will require special matching components such as increased compression ratio, multiple carburetors, head work, stick shift transmission, or very loose torque converter to operate correctly.
