Retails at $2150.0 up to $2400.00. This block has all the 4 bolt splayed mains included. I was going to use for a project but never got the project started. Multiple deck heights and bore sizes up to 4.600", the Big M Sportsman block gives you the versatility to build a wide variety of engine combinations. A true priority main oiling system oils the main bearings before the lifters for extra reliability. Features: - Standard 9.800" and tall 10.200" deck heights available for stroker engines. - Standard 4.250" , 4.500" or 4.600" bore sizes with siamesed extra thick cylinder walls to resist cracking and improve ring seal (minimum .300" thick with 4.625" bore). - Uses +.300" tall Gen VI style lifters. Modification for Gen IV style available. - Scalloped outer water jacket walls improve coolant flow around the cylinder barrels to equalize temperatures. - 4 bolt ductile iron main caps have splayed outer bolts for extra strength. - True priority main oil system lubricates the main bearings before the lifters. Our stepped main oil gallery (9/16" to 1/2" to 7/16") increases the flow of oil to the crank at high rpm, and our front oil crossover eliminates internal oil leaks around the distributor shaft. - Oil filter pad is drilled and tapped for an external oil pump. - Lifter valley head stud bosses prevent blown head gaskets. - Rear main cap uses standard oil pump and two piece seal - no adapter required! - Mechanical fuel pump boss, clutch linkage mounts, and side and front motor mounts simplify installation in any chassis. - Dual oil pan bolt patterns fit standard and notched oil pans. - Coated cam bearings, freeze plugs and dowels are NOT included.
