The Coast High Performance 5.1L Modular Pro-Street Short Block is one of the best solutions for a Mustang owner who's pushed their factory engine to the absolute limit of performance, but still wants more. CHP's short block was originally designed for 1996 to 2004 Mustangs with two or four valve cylinder heads.
CHP's short block is internally balanced and blueprinted for ultimate quality and features a 4340 steel crankshaft from Prob Industries with 6" H-beam steel connecting rods.
The Pro-Street short block features a 3.750" stroke and a 3.625" bore (optional) that are a huge step up from the standard 3.552" bore and 3.543" stroke to gain massive amounts of power. CHP's short block improves one the stock 4.6L V8's compression ratio by offering up to a 10.49:1 ratio when using two-valve 42.44cc cylinder heads. Call Stage 3 at 1-877-5-STAGE3 or 623-434-5277 for details on three-valve and four-valve heads.
