hello, I have been looking in the forum but have had no luck
I have a '01 silverado w/8.1L (496ci) it is based on previous chevy big blocks and takes pf454 (1/2 quart) stock and I upgraded to upf1218 (1 qt)witch is the same mount plate just longer case, both have a ADBV, I am about to run out of my supply of these and I am looking for alturnatives before I order a bunch more upt1218's these two are also base compatable with the pf25 (half quart) pf35 (one quart) and pf932 (2 quart GM heavy) except these 3 do not have a anti drain back valve, I would like to use a 2 quart filter like the pf932 but with a ADBV, I read that K&N has them on all of their filters but acording to their web site they do not make the pf932 equivelant
any idea's? it has a 13/16-16tpi screw (very common in chevy) and a very wide seal seat it would take several diameters. like most chevys the pressure relief valve and bypass valve are in the block, the filter only needs have a adbv
from what I have seen this is the same base as the 305/350/400/427/454/496 and lot of other chevy v8's just the length changes
ps, I have read (second hand info) that there is some changes in the manufacture of the upf's???? if I order some more upf1218's from GM parts direct will I still be getting the good stuff?
