Unless you are rebuilding the engine anyway, I would not waist my money. It
takes a lot of hp to gain any real benefit on the water. Most quote 15 hp
to 1 mph. Spend your money on a 350 assuming your boat is 18' or bigger. A
17' will probably run sideways from the torque.

Biggest bang for the buck is usually found by going to a good performance SS
prop. You can see 5 mph gain with the right prop over a cheap aluminum one.

I have done some research and heard you can put higher compression
flat-top
pistons in the 4.3 and gain a few HP. Who makes these pistons? I have done
a
bunch of searches and come up empty handed.

A related question, I have also read that the 4.3 is a 350 minus two
cylinders and that the pistons and rods are the same. Is this true or
false?
