#3) Stroke it! That will broaden your power range and power output dramatically.
If you must stick with a top end rebuild only, then the proer portwork and and a few other external bolt-ons would be your best bet, considering what you have to work with.
A lot of this depends on which year 460 you have.

The truck is a 78, but I have an 88 motor in it.
