[N. Joseph Potts]

I'm not an expert on this subject, but I don't believe 140s have a different
rocker-arm RATIO. The Chevrolet Parts Catalog (as well as Clark's) shows a
single part for 1960-1968. For 1969, the GM publication shows a different
number, but that number includes the ball, so I don't know what changed.
     I believe 140s have a different LIFT, and quite likely different DWELLS
(overlap) because of the engine's aggressive cam, but I do not believe the
arm RATIO was different. But I'll be watching this thread for corrections,
as I, also, recently installed all new Clark's arms (c766x) all around. I
THINK these arms may have been just SBC arms and balls - they looked a bit
different from the originals. But they seem to work quite the same.

Uh oh. I didn't know that, and I ordered a set out of Clarks book pn c766x.
I
knew that Corvair is different from SBC, but I didn't know about a different
ratio for the 140.

Where can I find more info on this?

Thanks.
