Mercruiser engine HP size ?s

What engine is a Gen 6 round port roller cam motor.
370 Hp or more.
4 bolt main also if this helps.

Same ? about a Gen 5 with no roller cam but 4 bolt main.
Thanks

All Gen V and Gen VI BBC have 4 bolt mains.

Roller cam or not, the low output 7.4L engines with peanut port heads, make around 330HP at the crank.
