The ATK G3508088 is a 350 cubic inch long block engine meticulously designed as a 50-state legal replacement for 1978-1988 GM Small Block vehicles. This engine is manufactured to meet factory specifications, incorporating tighter machining tolerances, superior quality components, and finer balancing of the rotating assembly to enhance performance and longevity beyond the original equipment. The high-strength cast iron block features a 4-bolt main, a 4.000" bore, and a 1-piece rear main seal, along with provisions for a mechanical fuel pump and passenger-side dipstick. It is also drilled and tapped for clutch linkage. The rotating assembly consists of a cast crankshaft with a 3.480" stroke, forged 5.700" connecting rods, and OEM specification pistons. The engine is internally balanced at the front and externally balanced at the rear. It is fitted with perimeter bolt iron cylinder heads and a hydraulic flat tappet camshaft with OEM specification lift and duration. Included with this long block are new valve covers, a rear sump oil pan, a timing cover, and a harmonic balancer. It is designed for compatibility with OEM GM TBI (Throttle Body Injection) and ECU (Engine Control Unit), and is approved for use with 87 octane fuel. The firing order is 1,8,4,3,6,5,7,2, with a total oil capacity of 5 quarts. Spark plugs are specified as ACDELCO CR43TS with a gap of .035".
