The Little M Sportsman block is the affordable alternative for sportsman racers and serious street performance. Eliminate the time and expense of ‘blueprinting’ a stock block. The Sportsman is brand-new, fully machined, and virtually ready to assemble with off-the-shelf small-block components. With extra-thick cylinder walls, ductile iron main bearing caps (4-bolt on the center three and 2-bolt on the ends), and a competition oiling system, the Little M Sportsman is the perfect starting point for a powerful and reliable engine for the street or the race track. You can select 4.00" or 4.125" cylinder bores, and 350 or 400 main bearings. Don’t waste time on a questionable junkyard block or waste money on machining a “semi-finished” factory casting.
Your block can arrive ready to assemble with freeze plugs installed, camshaft bearings installed and the cylinder block machined to your specifications. Please contact us regarding pricing for this additional feature.
