I have to agree with Bob and others who have mentioned that the correct
selection and setup of the camshaft will be the most important factor
for the engine in your Rampside. Even better results can be obtained by
prepping a good set of heads, either 110 or 140, to have good squish
effect and chamber volume to run 87 octane fuel. Also pay attention to
the engine RPM at your favorite cruising speed and what is needed to
climb hills, based upon your gear ratio and tire size. Don't do this
blind if you select an aftermarket cam. Use the wealth of experience
from the Corvair community and perhaps some computer modelling to narrow
the selection process.
