That sounds good. My old 496 with cast iron oval port heads, 11.5-12.0 comp, 1150 dom carb and a decent solid lifter cam made 635 Hp on our dyno. We converted many 2 bolt mains back in the day they worked out good..
If you can take a look at the main bearings and see how they are ask who did the work hopefully it was a reputable shop.
Maybe ask to have the block (line hone) checked by a machine shop first if it was never running after the conversion

Accelerating is optional...........stopping is mandatory. Your car WILL stop one way or another.
