Yes, you need to change the springs, they need to match the cam. Yes, you need to change the springs, they need to match the cam. Yes, you need to change the springs, they need to match the cam.

just a couple add ons will this increase my horsepower with these add ons what size carb and cam lift would be good for this set up,

Just a couple of add on will increase HP, but not just any thing thrown on.
Since your not to concerned with actual speed, just to sound tuff, try a cam that will work with the cars gear ratio and stock stall converter.

Lots of lift is not important, the cams duration is. Try this MP cam; http://www.summitracing.com/parts/DCC-4452759/
A 500 cfm Edelbrock carb
some Dyno Max mufflers, dual exhaust @ 2-1/2 inch pipe.

I would also get a MSD 6 box.

The possible hard part is the year of your engine. It has odd bolt angles and use small 5/16 intake to head bolts rather than the extremely more common 3/8.
