HerrOtto,

It would be interesting to see what performance might be gained from in HEI in stock 216/235/261.

I saw no performance difference using a Pertronix unit in my 270ci 261 with dual carburetors and dual exhaust. Most likely, I almost never rev the engine to over 3000 RPM (80 MPH).

I'll set/check points.

The 216 and early 235 engines are not "splash oilers" -- this is a splash oiler.
