If your going to reuse it in a truck or motor home I would check the bores first for taper and wear first and go from there I would try to duplicate the original parts for the heavy duty use They where designed to be ran at or near WOT for long times and live carrying a lot of weight I don't remember what RPM they where governed at but it was not above 4500 RPM if I'm thinking correctly
CABster .... I’ve talked to several people who have used these blocks for HP use and taper and wear were never an issue they saw. NEVER MUCH sludge build up because the motor is so heavily loaded PLUS low miles. I have one part apart up in Michigan that has ZERO sludge !
