How to make my '79 Commander sound like a '73??

I can say firsthand that the smaller chamber heads will raise compression and flow better to give you 30-40 horsepower more.
At sea level it made my boat feel much more powerful .
I installed my new heads at 1,000 hours and it still sounded and ran like new when I sold it some years later with more than 1,500 hours.
My buddy liked to one foot at 45 mph, this boat at sea level did that without running wide open. He owned a new 2001 hull at the time that was BLACK. Only Black 2001 I ever saw.
He could not one foot in his boat it did not have enough Speed. This was 1983.
You will see a difference.
If you think it will be weak start looking for a 454 to swap in.

Hey JoeinNY - Finally got a look at the prop and it is in fact an Acme 542. Good call, that might explain why the boat seems to be performing so well!

I'm going to mention this and have some questions on the other thread I started in General Discussion.

I guess the missing belt and water hoses must have been options

Thanks for the stock photos ultra! - I hadn't been following this thread since I started the '79 build' thread.
