Looking for more pep off the line

I think he fell into the same hole us novices like myself fall into. 73s are heavy freaking cars. Mine is 3480 without me, 3700 with me. fiberglass hood, aluminum heads, bumper reinforcements removed and no heater box. No other options to remove weight unless I acid dip the car which isn't happening. I have a MP 380 hp crate motor, stall and 370 gears. The car is slowwwwwwwwwwwwww and only runs 9s in the 1/8. Going to need a higher hp motor. Put the same motor in a significantly lighter 70 to 72 duster and you are going somewhere.
