Yo man, I'm right phukin here. You got a problem with me?

I saw a 496 for sale that had 710 HP and ran on pump gas. 710 HP will get that boat into the 90's. There isn't any info on that 509 ci Chevy, for all we know it has 16:1 compression, runs on alcohol, has a huge cam, and twin turbo's. It is very possible that the boat does over a 100 mph with the info given in the listing. As far as the guy only doing 85 mph passes, maybe he's scaired?

I probably will be too, if and when I ever get there.
