Upgrade/replace your tired or exploded bottom end with our new, professionally assembled, race ready 240cc short blocks. We start with a bare 72mm Tillotson block that we inspect and prep before installing a C3 case bearing and seal, then load it with a 59mm crank, EC forged connecting rod and Tillotson hypereutectic flat top racing piston, your choice of Dyno Cams 224-240 camshaft (compression release) mated to OE forged Honda lifters and seal it all up with an ARC billet side cover.
