Dart Introduces Special High Performance Small-Block V8
Dart's new Special High Performance (SHP) small-block meets the need for an affordable, precision-machined cast-iron block with superior features. Designed for high-performance and heavy-duty applications producing up to 600 horsepower, the SHP block is the ideal starting point for hot rodders, drag racers, circle track competitors, off-roaders, and high-performance marine enthusiasts. Two part numbers cover the vast majority of small-block engine combinations: 31161111 (4.00˝ bore) and 31161211 (4.125˝ bore).
Made in the USA on all-new tooling, the SHP block delivers exceptional value. Priced hundreds of dollars less than a full-race block, the SHP block eliminates the time and expense of rebuilding a junkyard core. The SHP block is tailored to the most popular performance and racing applications, with 350 main bearings and a choice of 4.00˝ and 4.125˝ cylinder bores.
SHP blocks are manufactured on Dart's in-house CNC machining centers to precision tolerances. The SHP block's siamesed cylinders have a.230˝ minimum wall thickness at 4.165˝ bore diameter. Other features include a true priority-main oiling system that ensures reliable lubrication at high rpm, ductile iron main bearing caps (with splayed four-bolt caps on the center mains), .625˝ thick decks with blind head bolt holes, and clearance for long-stroke crankshafts.
The SHP block retains the first-generation small-block's original dimensions and is compatible with stock components, including OEM-style hydraulic roller lifters and camshafts, steel and plastic timing chain covers, side and front motor mounts, clutch linkage pivots, and mechanical fuel pumps.
