If you are going to use a full-flow filter on 228/248/270/302 GMC engines that have not been converted for full-flow filtration, should you put a restriction in the inflow line to the filter (maybe put in the hose-to-filter-head fitting a washer with a 1/8" opening/restriction)?
I think that is what has been recommended when a full-flow filter is used on standard 216/235 bocks and on pre-1958 261 block?
Troy, are you looking for the filter unit/assembly, or are you looking for the filter cartridge?
