Big M Sportsman (4.500 x 9.800) Product Description:

Bore Size: 4.500    Deck Height:  9.800


The Big M Sportsman block was designed to be an even more affordable version of our highly popular Big M. The sportsman block is fitted with ductile iron 4 bolt main caps, and features a redesigned lubrication system that oils all of the main bearings before the lifters for added reliability. We added two slotted head stud bosses on both sides of the lifter valley so you can use studs instead of hard to install bolts to take the place of the "missing" head bolts. Available in 9.800 & 10.200 Deck heights and bore sizes of 4.250, 4.500, and 4.600, the Big M gives you the versatility to build  a wide variety of engine combinations. We can finish your block with all labor operations, install cam bearings and freeze plugs, and give you a 25% discount on total labor charges!! Don't forget to ask about rotating assemblies to save even more & our price includes all ground shipping charges to any address in the continental U.S.
