720 is race fuel only. The 620 is not and I believe Eliminator used one in a boat recently

I was considering these motors (the 620 HP) but I didn't know enough about them and I was hearing good/negative things about these motors for a boat. the GM add says that NO warranty if used in a boat.

GM has been having very good results with these engines.

We supply the carburetors for them. The only problems we've really had with them, is that they haven't been able to build them fast enough.
