Revolution XSR 204-204 Stock Replacement Hydraulic Roller Camshaft

204/204: "Revolution XSR" 204/204 Stock Replacement Hydraulic Roller Camshaft - Stock Replacement Roller Camshaft - For Stock Rockers! 

Specifications:

Introducing our Revolution XSR 204/204 stock replacement roller camshaft for the 1986/87 Turbo Buick GN & T-Types. We have had many requests for a hydraulic roller camshaft that can be installed in a car without removing the heads and matching the valve guides for retainer clearance due to the high lift that usually comes with these cam conversions.  This cam will go right in, no machine work needed, will provide a nice performance increase  but also provide the peace of mind that comes along with a roller cam and not losing a lobe like flat tappet cams are so prone to doing.

• Duration at .050" Intake - Exhaust: 204/204
• .440 /.440  valve lift @ .050" with stock 1.55 rockers.
• 111* Lobe separation - installs at 109.
• Substitute PAC-1219 Springs for PAC 1218 Springs
