What is the best way to remove and install an oil pickup onto to a new oil pump. Been going through my 351/4VCleveland, It has 96,000 miles on it. Not much carbon (black though) and all the bearings are clean, unscored and show now signs of wear. Bores haven't been bored and don't show any signs of abnormal wear. I'm thinking of cleaning it up, putting in a new cam and running it for a year before doing a thorough rebuild. Also wondering if it is possible to get accurate compression tests on cylinders with the engine out on an engine stand. If I install the heads and crank the engine by hand will i get useable results or does the engine have to be at operating temperture.
