Good points, Carl,
I am concerned about starting (breaking-in) the 235 that is being rebuilt for me. I have a Holley-rebuilt Rochester (not tuned-in) and my old Rochester (which has not been run for over 10 years).
My solution is to set-up the rebuilt Rochester on a friends truck and check-it/tune-it. Then, it should be good-to-go for breaking in the cam/lifters/etc at the start-up of the rebuilt 235.
