The Old Master was invited a few years back to one of our Sidewinder SCTA meetings. He was very nice, and it was fun to listen to him talk about all kinds of racing engines. When quizzed about the cammer, he kinda danced around trying to think of nice things to say.
It went something like this:
On nitro, the blocks were junk.
Between rounds maintenance was impossible...if the heads needed to come off...pack-up, yer go'n home.
Kind'a destined to fail as a nitro burner...but man, they could make good power.
