a set of AFR 165's with a stealth and that carb would scream..
I'm running afr's,a port matched performer on my 84 with a holley 600 and it pulls to 6k before the power drops off... with the stock cam and 1.7 rockers...
oh yeah, you might want to go with a high volume fuel pump too..holley or carter.. and a good coil.. like and MSD blaster 2..
