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.

This is a high intensity camshaft with very fast ramps and higher lift. It is for the guys who want to make the max power but still keep the RPM’s within reason. It is offered with fully ported heads, big turbos and high stall non-lock converters in mind. We used to run this cam in our old TSS setup with great success. It requires a stronger valve spring (PAC1219) that we will offer in the kit when this cam is selected. Roller rockers and at least iron heads are required-- 1.55 ratio is best for most applications; 1.65 ratio is not recommended.
