If I was compelled to do something, it would be buy the smallest combustion chamber, low cost aftermarket aluminum head (Eddy EStreet?) and something like the Crower 271 cam. You'll probably be closer to $2000 when done, but will probably put 40+ HP in the motor. Then upgrade exhaust and induction as $ allow. You could get close to 380-390 HP and won't need to change your torque converter. twocents
probably won't need that 3.91 gear either. adding a simple ring and bearing job would be nice.

my "spare" engine has a set of hugh's '452's with kb184 pistons and a howards cam similar to the crower. haven't used it yet but I guesstimate a solid 380-400hp with mufflers and accessories hooked up. this concept would be a nice pump gas driver.
