Mine came with a pair of blown big blocks from the factory but they blew up in 1999 and the previous owner to me put the stock 420's in it with single carbs. (runs just about as good and less fuel!)
Here are some pics below of before and after.
This is the stock engines from factory with the blowers.

This is what it looks like now with the stock 420's

Went from 65gph to 35gph. Quite a difference and still scoots along the water pretty good.
