Inliners International Forums General Discussion Engines GM 4 cylinders 151 153 181

Does any one want to talk about GM 4 bangers? I just got a '80-'81 Iron Duke rebuilt long block. I thought they used the same bellhousing as our 6s but it's the same as the 60* v6, some S10, Jeeps, and Dodges. I want to use a trans with a standard Chevy bolt patern. It has a cross flow head. They are strange looking. Will the 181 crank fit the 151? Will a SBC flywheel fit? One piece main seal? There are two holes on the right side of the block that have cam drive gears in them. One is for the distributer. What is the other one? I think I may have been better off just buying a 181. Beater
