Hi guys, I'm putting a 1971 400 in my 67 firebird with Long Branch exhaust, the angle oil filter housing I bought from Kauffman racing does not work as the exhaust hits the oil filter at midway on the filter. According to some research I need the 1966 GTO filter housing that is at a 120 degree angle. Anyone have one, know where I can get one or a way to fix it without returning the Longbranch ad going stock manifolds. Thanks text me at 949-795-193three if you have one. Engine is on the EZ run stand waitng to fire up.
