Hey guys, I have a 1986 4x4 automatic s10 with the 2.8 v6. Honestly its the truck I want, but it doesnt have the guts i want. I want to upgrade to a 4.3 out of a 91 I found, but I want to make sure everything will bolt directly. Will I need a different tranny? Bell housing? Anything? I know it will fit the engine mount, just not sure about the rest. Thanks in advance!
