Do you know anything about the K&B 3.5 model 8935 ? Seen it has a little more H.P. and RPM .
that is there SS version, same engine but air cooled. Also has a tune pipe/muffler on it thats what giving the extra .2 hp and the extra RPM's.
There are quite a good number of guy's that uses the K&B for racing, they use the power head and replace the lower unit with a lawless unit and then they add a good tune pipe.
makes some wicked Tunnels.
