GS-350-110. Our high performance cam designed for 1971 and up 350 engines with low compression ratios. Saves the costly expense of changing to higher compression pistons. 20 horsepower over the factory GS 350 cam. Super power and torque up to 5300 RPM. Will rev to 6000 RPM. Greatly improves power, torque and acceleration without affecting drivablility. Excellent throttle response. Smooth idle with very slight lope. Will not hurt gas mileage. Works great in a completely tock car although our headers and 350 Poston intake manifold will provide an additional and substantial power increase. Use Hi-Rev Lifters. Will work with stock valve train although we highly recommend our PE104 chrome silicon valve springs. Works with stock gears. $139.00

GS-350-113. Our high performance street cam designed for 350 engines with stock 1968-1970 or higher compression ratios. Ideal replacement for stock 350 cam. 20 horsepower over the factory GS 350 cam. Excellent power and torque up to 5300 RPM. Power is concentrated between 800 and 5300 RPM. Will rev to 6000 RPM. Power, torque and acceleration are greatly improved without affecting drivability. Excellent throttle response. Smooth idle with very slight lope. Will not hurt gas mileage. Works great in a complete stock car although our headers and 350 Poston intake manifold will provide an additional and substantial power increase. Use our Hi-Rev Lifters. Will work with stock valve train although we highly recommend our PE104 chrome-silicon valve springs. Works with stock gears. $139.00

GS-350-114. Our best selling street/strip cam. Notched pistons are not required. 30 horsepower over the factory GS 350 cam. Gobs of power and torque up to 5500 RPM. Power is concentrated between 1500 and 5800 RPM. Maximum RPM is 7000. Offers excellent driveability and low end response. Dual pattern and wide lobe centers provide a smoother idle than normally expected in a shot street/strip cam. Idles with slight lope. Works great in a completely stock car although our headers and 350 piston intake manifold will provide an additional and substantial power increase. Excellent gas mileage. Perfect 350 street/strip cam. Needs our Hi-Rev Lifters. Will work with stock valve train although we highly recommend our PE104 chrome-silicon valve springs 3.23 or larger gears are recommended. $139.00

GS-350 118. Hot street/strip cam. 35 horsepower over factory GS 350 cam. Good sounding lopey idle. Tremendous power and torque up to 6000 RPM. Best shift points are 5500. Power is concentrated between 2500 and 6000 RPM. Wide lobe centers make for a hot street/strip cam that works like a much milder cam. This cam would be too wild for the street if it were on closer lobe centers. Works best with headers, 2500 converter and 350 Poston intake manifold (many 350 cars have run mid 13's at over 100 MPH with this combination). Notched pistons not required. Works with power brakes and steering. Easy on valve train. Good gas mileage. Must use our PE104 chrome-silicon valve springs and Hi-Rev Lifters. 3.23 or larger gears are recommended. 9.5 to 1 or higher compression pistons are recommended. $139.00

GS350-112. Super hot street/strip cam. For the serious street racer who wants the hottest cam possible for street use. Needs headers and Poston intake manifold.

Will work with our PE104 springs. although we highly recommend our PE107 dual valve springs and PE108 "No Wiggle" retainers. Must use our Hi-Rev Lifters. NEeds 3000 stall converter and 3.50 or larger gears. $139.00

GS350-111. Biggest cam made for the 350. We recommend it for race or very limited street use. 3500 to 6500 power range. Pulls hard and makes lots of power to 7000 RPM. Super crisp throttle response. Idles at 1100-1300 RPM. Produces 60 horsepower over stock cam. Good for extra .6 and 6 MPH in the 1/4 mile. Must use gears, converter, headers and Poston intake manifold.
