JE Pistons Tour Series Gas Ported Pistons 170692

JE Pistons Tour series gas ported pistons have undergone engineering changes to handle higher horsepower 4-barrel applications (approximately 650 hp) and angle-milled heads. Both the 350 and 400 Series accept oversize valves (the intake pocket is 2.255 in. and the exhaust pocket is 1.870 in.) and long-duration, tight lobe separation cams. Ring grooves are precision-machined for .043, .043, 3.0mm backcut rings with lateral gas ports for a superior ring seal.Brand: JE Pistons
