what kind of hp/torque did it make
|
You can buy an out-of-the-box cam that kind of gets close to what might work and take a chance on leaving horsepower on the table- or destroy your motors with reversion...
Or you can call Bob Madara and get a cam that is 100% ground to match exactly what is in your motor, what your boat is and what exhaust you have. After a half-hour conversation with Bob, you'll have a better understanding of the different aspects of cam design and how they affect what you're looking to do. Best of all, you will ennd up spending about the same $$ as you would on an out-of-the-box cam and you'll save significant $$ on the other parts you'll need. Marine Kinetics (585) 654-8583 |
Talking to Bob is worth every penny.
Actually the custom cam is not that expensive. |

Bob's cams are less than a Crane roller cam from Summit !! And it is the right stuff !!

yes advanced a smidge . could use a little more lift , but for the added stress on the valve train for marginal gain hp wasn woth it my engine builder said !we also cut it on a 109 ls to get this thing moving a little quicker down low <
