I was wondering what rpm all you BBF guys are running at WOT... I am gonna be rebuilding my 460 Ford over the winter, and my engine builder is telling me it will cost a fortune to get the motor to tach over 6500rpm reliably... Main problem is its going in a jetboat, so i need it to tach 6500 to get any real speed out of the boat...
What kind of RPM numbers (and speeds) are some other fellow BBF jetboaters getting? I am looking for 80-85mph, and i am prepared to spend 6000-10000 on the motor (including new headers)... any help would be great.
