The B/RB chrysler engines do share that fact with the " other brand", that is when you line up the marks as per the manuals you are actually putting #6 at TDC. The nice thing is that the engines arent smart enough to have ever read the FSM so they really dont care. And as was stated if you dont remove the distributor it wont care either because its not any smarter than the rest of the engine. Mikey 62 Crown Coupe
