What I was really looking for was info on "no overlap" cams. Being a
child
of the sixties I cant imagine this.
Arch,
I'm not sure there is such a thing. I have never used a camshaft that
didn't have some overlap. I believe it is of some advantage as the
incoming charge helps evacuate the cylinder, to a point, that is. Some
of the performance camshafts have so much overlap that it actually works
to some advantage in that at lower rpm it reduces cylinder pressure
allowing the use of reduced octane gas. I got some understanding of
this when people kept swearing that they were running todays gas on
yesterdays 10.5:1 engines & not having any detonation problems. (375 hp
396's etc.) RV cams to the best of my knowledge have minimal overlap.
I also believe that most of today's technology is not so much towards
camshaft design as it is in cylinder head technology. They just keep
getting better & better.
As a child of the 60's, how young are you?
