Thanks for your help with the neighbor's car.
We replaced the points and condensor and adjusted the valve clearances with an old set of shims that I had leftover from my 142. It runs 90% better as a result.
Took it up on the freeway and it keeps up with traffic but sounds winded. No tach but going by ear the engine speed must be in excess of 3,000-3,500 rpm at 70mph. This is a '67 with B18B and M40. Don't know the diff ratio. About how fast is the engine running at 70? 75? Is there anything wrong with my neighbor using this car for a 30 mile R/T highway commute? Premature engine wear or just a decrease in fuel economy?
My 142 had overdrive and I almost never drove in 4th with the O/D off under 45-50mph.
Thanks again.
