I'm about to order a Chapparal 190 I/O.

I can get either the 3.0 Volvo or the 4.3.
Can someone tell me the difference in speed between the two.

I understand that most recommendations will be to the larger engine, but
cost is a consideration at $2000 higher for the 4.3.

Before I make a decision, can I get some factual differences between the
two?

Thanks a lot in advance.
Dave
