most you will gain on a 4.3 is about 3-5hp

you will gain more by simply unbolting the crappy heads and bolting on a set of vortec heads (1996 and later)

and why did you post in the non-repair outboard forum?

I was just asking a question, im not looking for any horsepower for speed. Scott respectfully speaking your a hard guy to talk to. I was just asking a question.
