The truck has a 235 now, but I want a bigger six. I'm considering a 292 or a 302, whichever seems easiera ns which ever comes along first. I just want to know what is involved with each swap. The truck does have a hydraulic clutch, with the clutch lever and slave on the passenger side of the bellhousing and I would prefer to keep that set-up rather than change to a mechanical linkage clutch.
