lose the single exhaust , dual 2.5 or 2.25 will do fine with good freeflowing lers.

ditch the tbi , swap on a performer or rpm intake with a 600 holley vacumme

a set of mid lenth or shorty headers will help

set timing up 12-14 deg with premium fuel 89-93 depending on conditions

a 3.73-4.10 gear and limited slip will make the car feel quicker also
