I have a 1966 Vette 427 Engine. It was rebuilt a couple of years ago and I put it in a 65 3/4 Ton P/U. It is fun to drive and suprises a lot of people, (truck is pretty ragged looking), but is way to much motor for the truck. So...... I got to thinking. What if I transplnat it into my boat.
It is 2000 21' Glastron with a 5.7GSi 280hp at the prop motor, hooked up to a 2000 Volvo SX/Duoprop drive. The boat weighs in at around 3250# loaded and runs 65 on the GPS now.
Questions:
1. Is the motor at, 425 HP & 475FTLBS of torque, too much for the drive.
2. What are the hurdles I face in switching out with the BB.
3.Cam suggestions, manifold, or ???
4. REALLY-REALLY important question how much faster would the boat be????
