Gen III / A body...high 10's / low 11's...street strip car. Anyone?

SO EFI Source Duster on 93 octane, 4.10 gears 727 auto 8" 4800 stall 3300pnds ran 11.52. He did say the converter was a little hard so 9 1/2 would be better. This was a stock 6.1 with 80m TB and their out of box tune. 6.1 makes 385 wheel and with a cam should make around 415hp wheel and that should be enough with a lower stall to do mid 11s because his friend with a 2900 pound duster and i think little higher stall did 116 at 11.00 flat. I am happy with low 11 or high 10 if I can get it with little money put into the engine besides cam and headers and TB.
