I have a 460 pi in a 18ft baja hull . The pump is no good and I have to take down and rebuild the engine. I want to get as much hp on pump gas as possible. And be able to ride around on the weekends.

Yes, as long as the tires on the trailer are in good shape and the tow truck has 400 plus horsepower.:D

Eagle has a new stroker kit for around $1400 no clearnce required comes crank, h beam rods, and pistons. Bored 100 over comes out to 557 ci. With that and alum heads you can run 11:1 comp on pump gas and get close to a 100 mp.

100 mph with a 460 jet boat, yes, it's possible, but not with the engine in "stock" configuration. Most stock 460 jets will run in the upper 60's to mid-70's, depending on hull design, weight, and set-up.

As for going 100 mph in an 18' Cobra, not sure I'd want to, except to make one GPS pass just to be able to say "See!"

I have a couple friends that have stroked 501 CI Ford's, one in a 18 BAJA , one in a Taylor LP both boats are running mid 70's with considerable pump work. Don't think the BAJA is capable of triple digits, both boats are on the edge as it is.
