On my FED the motor plate is drilled for late Chrysler and BBC/SBC When my BBC is bolted in, there are partial holes showing due to the Chrysler pattern, is this a problem ? Also is 40" from axle centerline to back of motor plate enough room for clutch can (8 5/8"-8 1/8") and 2 spd lenco with reverser ? I realize I might have to slide engine forward to service trans that is alright just not sure if it will fit. couple years back I was told a min. dimension and can't find it in my notes. I plan on going to clutch and 2 spd set up in future.
