Re: how to get the most from your motor...

cam seems to be right in the wheel house of working with your combo. 1800 - 5000 so if you stall in the 2000-2500 range it will pep up nicely So I definitely start with a easy swap of a stall converter which will make a great difference out of the hole with that camshaft.
