GM Performance developed these ZZ4 crate engines, which are evolved from the popular ZZ series of small blocks that power thousands of street rods, hot streetcars, circle track racers and drag racers. These ZZ4 350 c.i.d., 4-bolt main, 1-piece rear main seal crate engines have approximately 10.0:1 compression, 355 hp at 5,250 rpm and 405 ft./lbs. of torque at 3,500 rpm. To make this package work GM Performance has installed forged 1053 steel internally balanced crankshafts, 5.7 in. powdered metal connecting rods with hypereutectic flat top pistons with offset pins. Hydraulic billet steel roller camshafts are installed with .474 in. intake lift, .510 in. exhaust lift and duration at .050 in. for intake is 208, and exhaust is 221 and a lobe centerline of 112 degrees. Stamped steel self-aligning rocker arms with a 1.5:1 ratio are used on cast aluminum 1987-91 Corvette L98 cylinder heads. Which have 58cc combustion chambers, 163cc intake runner volume. They have a 1955-86 bolt pattern with "D" shaped exhaust ports and center bolt valve cover patter layouts, no exhaust heat crossover passages and the ends of the heads are drilled for standard accessory bolt patterns including angle plug configurations. Aluminum dual plane intake manifolds with dual flange set up. Cast iron Long style water pumps are used with standard "V" belt rotation and 1979-86 power steering pump bosses. GM HEI large cap with internal coils are installed to deliver the spark. With a long history of successes in circle track and drag racing as well as street rods and other performance applications the ZZ4 may just be the bullet for your next project. These ZZ4s are not intended for marine use and should only be used in 1973 and earlier pre-emissions street vehicles or any rear off road vehicles.
