Here is a link to an archive article of a builder in Florida who also used a 4.3L V6 in a Barrel Back. He may still be in contact Butch Barto (on the forum) and could give you some insight as to what prop he is using and some performance numbers.

I run a 13x16 w/1" shaft on my Tahoe at 20'6". I have a 125/115 Yanmar diesel (3900 rpm) w/1.23 reduction gear. That means that I only turn about 3000 rpm at the prop. I get WOT of about 38 mph or 61 kph. The next 10 mph or 16 kph will take about twice the HP. 16/1.23 = 13 pitch. I think the BB and my Tahoe will be close in weight. My boat is a little bigger. But, your engine is bigger.

I think 13x13 is right.

Thanks Bill,
Glad your there. As always, I'll take your advice.
Martin.

Ps: I have a fair bit of sanding to do... fancy a holiday in the UK?
