I've had some success with the following set up: stock 1275 lower end, aluminum
head with hardened valves( makes it no lead compatible), Kent 266 cam, belt
drive for the cam, LCB header, and 45 DCOE Weber. Did some blending on the head
and switched from the Bosch plugs that came with the head to Champion RA6HC
plugs, B210 5-speed, 3.9 rear end. Seems to run well, needs some tuning on the
Weber. The engine is in a 1960 Bugeye that just got running before the Healy
Conclave. Much more work to do on the body and on the inside.
