Anybody know if the 3.8L Buick FWD engine and the 2.8L/3.1L/3.4L Chevy FWD share the same bellhousing pattern? I thought so originally until I found out that the Quad 4 and the 2.8L are different. So maybe the Buick is different too. I am not talking about the RWD engines. FWD only. Thanks Terry Kelley
