Jack started this build with a standard 580 West Bend block then proceed to cut the head off and tap the block top to accept a Mc 10 cylinder head. Once the head conversion was finished Jack then add external boost ports to feed alky thru a McCulloch carb into a Go- Power manifold which fuels a flat top Power Products piston pushing the exhaust out of a Azuza header. Essentially Jack has convert this little Bender from cross scavenge to a loop scavenged design.
Once the engine was finished it was bolted to a 1961 Go- Kart 800 and I'm here to say she runs like a beast.Coming on to the straighaway at Fremont while following a piped Mc 91 and a West Bend 820 I figured I was going to get pulled down the chute but no, that little Bender kept right up with its bigger counterparts.
