CHEVY SMALL BLOCK
TOUR SERIES GP (GAS PORTED)
|
Similar to the Ultra Light GP, this piston has undergone engineering changes to handle higher horsepower 4-barrel applications (approximately 650 hp) and angle milled heads. Both 350 and 400 series accept oversize valves (intake pocket is 2.255" and the exhaust pocket is 1.870") and long duration, tight lobe separation cams. The ring grooves are precision machined for .043, .043, 3mm back cut rings with lateral gas ports for superior ring seal.
