Question

Need some experienced input. Bought an old 66-67 396 and noticed that previous owner installed a trans dapt oil filter adapter to use screw on filter vs. canister type. I read in a BBC big by Ed Staffel that you must use the original by pass valve in conjuction with the kit or you will end up bypassing the filter itself without it. Summit has a note that only the 13/16" nipple kit requires the use of the filter bypass valve. Mine is a 3/4" nipple and there is no filter bypass valve in the block. Am I ok oor am I bypassing my filter? Please help before I fire this thing up again. Thanks.

Two things first are the 2 bolts that hold the filter adapter on 1/4 or 5/16 If they are 5/16 you don't have any problems if they are 1/4 then you have an early block. The bypass they are talking about is in the factory filter adapter. Most adapters leave this in and go over the top of it but I don't know about yours. also you will need a groved cam if you don't have a solid lifter cam.

oger's right on
but they also have grooved rear cam bearings available so there is no longer a need for the special cam, make sure the engine has one or the other, (NOT BOTH)
I had an early big block and just ran the Trans-dapt thingy without a hitch, be carefull though, the Orings on those things SUCK!! Be real carfull when installing it not to pinch the o rings on the block housing, I installed mine several times before I got it to seal right.
