Buick


CAUTION: Do not attempt to operate an engine with less than .150” retainer-to-guide clearance. If you are using valve seals, check the clearance from the top of the seal rather than the top of the guide.

CAUTION: Due to the unusual chamber design in the Buick cylinder head, valve-to-piston interference is always a problem. We recommend checking clearance on any camshaft of 290 degrees of duration or more.

WARNING--Some early Buick engines used 11/32” valve stems with 11° steel retainers. Only use matched components. Failure to do so may
result in serious engine damage.

CAUTION:
Not all optional high-performance parts for early Buick, Oldsmobile and Rover engines are interchangeable. Please call Erson’s Technical Service Team at 775-882-1622 for assistance selecting additional components

WARNING--
Some early Buick engines used 11/32” valve stems with 11° steel retainers. Only use matched components. Failure to do so may result in serious engine damage.

TECH TIP:
When installing these cams, valve-to-piston clearance must be checked as there is a possibility of valve-to-piston interference. We recommend .080” intake and .100” exhaust minimum clearance.

TECH TIP:
When installing a hydraulic lifter racing camshaft in an engine that does not have adjustable rocker arms, care must be taken to ensure that the lifter is still able to adjust itself. If the camshaft has more than .500” valve lift or the heads or block have been milled excessively, the engine must be converted to adjustable rockers or adjustable pushrods.

CAUTION:
 Due to the unusual chamber design in the Buick cylinder head, valve-to-piston interference is always a problem. We recommend checking clearance on any camshaft of 290 degrees of duration or more.

1968-80 350 CID H, J SERIES


TECH TIP:
When installing these cams, valve-to-piston clearance must be checked as there is a possibility of valve-to-piston interference. We recommend .080” intake and .100” exhaust minimum clearance.

WARNING--
Some early Buick engines used 11/32” valve stems with 11° steel retainers. Only use matched components. Failure to do so may result in serious engine damage.

NOTE:
It may be necessary to use stock OEM style valve locks due to an atypical 11° taper at the retainer.

NOTE:
Late Model Buick 350 cubic inch V8 engines have several different valve spring installed heights. The two most common are 1.727” and 1.670” using a 1.300 O.D. spring. For assistance, in selecting these and other Buick valvetrain components, call Erson’s Technical Service Team at 775-882-1622.
