have a '76 boat that has 220 hp chevy's in it, built/assembled by crusader marine. The motors are either 305 or 307 chevy blocks. One is reverse rotation. The powertrain setup is the motor, bolted to a transmission, bolted to a walther v-drive, all 1976'ish era. If i should ever decided to mess with it or it's sold, will a late model chevy vortec 350 bolt right up with the transmission and bellhousing? Is the bolt pattern the same?
