This little rooster brings the piston bore size closer to the crank stroke length for a real smooth linear rip. Safely pull some high revs with this closer to square over big bore. Our first choice for a solid road race/street engine running big boost numbers. Maintains the 8.5:1 compression for use with forced induction. Includes BBM custom forged 83mm pistons, HD tapered wrist pins, reconditioned rods with ARP fastner upgrade. This engine is assembled using only German OEM gaskets, seals and bearings to ensure complete reliability. The oil pump is replaced with a high volume unit. All reciprocating parts are digitally balanced, parts/clearences blueprinted.
