Product Overview
FASTTIMES BBC PERFORMANCE AFTERMARKET SHORT BLOCKS ARE BUILT WITH THE SAME CRAFTSMANSHIP AND QUALITY AS OUR RACE ENGINES. UNLIKE SOME OTHER SHOPS, WE MACHINE, BALANCE, AND ASSEMBLE OUR ENGINES 100% IN-HOUSE. THIS GIVES US 100% CONTROL OVER THE WORK THAT IS PERFORMED TO EACH COMPONENT.
THEY FEATURE A DART BIG M CAST IRON BLOCK. EVERY BLOCK GOES THROUGH A DEBURRING PROCESS THAT CHAMFERS CRITICAL EDGES AND HOLES TO PREP FOR MACHINING. THEY ARE THEN ALIGN HONED TO ENSURE THE MAIN HOUSING BORES ARE THE SAME SIZE IN SPEC AND IN LINE. AFTER LINE HONING THE BLOCK IS MACHINED TO ENSURE THE DECK SURFACES ARE PARALLEL TO THE MAINS TO A NOMINAL DECK HEIGHT OF 9.785". NEXT THE BLOCK IS BORED AND THEN FINISH HONED TO SIZE. THE LIFTER BORES ARE CHECKED AND HONED TO SIZE AS NEEDED. AFTER FINISH MACHINING THE BLOCK THEN GOES THROUGH A FINAL PREP PROCESS THAT INCLUDES ANY EXTRA CHAMFERING OR DEBURRING THAT MAY BE REQUIRED BEFORE FINAL CLEANING.
THESE SHORT BLOCKS COME WITH A QUALITY FORGED STEEL CRANKSHAFT, CONNECTING RODS, AND PISTONS. ALL CRANKSHAFTS ARE SPIN BALANCED ON OUR SUNNEN BALANCER TO WITHIN ONE GRAM ON EACH END OF THE TARGET BOBWEIGHT THEN MICRO-POLISHED FOR A PERFECT FINISH. EACH CONNECTING ROD IS CHECKED FOR HOUSING BORE ROUNDNESS, TAPER AND SIZE. ANY ROD THAT DO NOT MEET THE HOUSING BORE SPEC IS MACHINED TO SIZE AND ROUNDNESS. PIN BORES IN THE RODS AND PISTONS ARE HONED TO SIZE FOR PROPER OIL CLEARANCE FOR THE APPLICATION.
ALL COMPONENTS GO THROUGH HAND FINISHING AND A MULTI-STEP CLEANING PROCESS TO ENSURE THE BLOCK AND ROTATING ASSEMBLY ARE FREE OF CONTAMINANTS BEFORE ASSEMBLY.
