Speed-Pro Performance Hydraulic Camshaft Chevy 262-400 2000-4500 RPM Part #: CS1169R
Chevy 262-400 cid Hydraulic camshaft, 2000-4500 RPM Range, 292 intake/292 exhaust Adv Dur, Duration @.050 218 intake/218 exhaust, Valve Lift .458 intake/.458 exhaust, Lobe C/L 110. (I'm sure they meant to say Lobe Separation Angle 110 degrees).
Very lazy lobe design, obsolete design, Hydraulic Intensity of 74. Current cam grinds are in the 45-60 Hydraulic Intensity range. Will work OK if motor is between 8.75:1 and 10.0:1 static compression ratio. If motor is less than 8.75:1, it will be a pig with that cam. If motor is over 10.0:1, it will probably detonate due to excessive cylinder pressure and the inability of iron heads to shed heat as well as aluminum heads. You fellows who just pick a cam out of thin air without figuring the exact static compression ratio are shooting yourselves in the foot. Could work, could not work. That's one hell of a lot of money and labor to put your faith in a "maybe".
