How would you build a low 10’s street car

I wonder how fast that engine would be in a 2800 pound a-body with a back half?
60 Foot E.T. : 1.29
1/8 Mile E.T. : 5.85
1/8 Mile Trap Speed : 116.23
1/4 Mile E.T. : 9.27
1/4 Mile Trap Speed : 145
He paid about $12000 for the engine, pro built and dyno'd@EDA, new pistons/rods/crank/cam etc., we were lucky it came through the racing fraternity, wasn't enough hp for most and a mismatch of parts really, low comp/small cam/with race heads but was perfect for us as a street/strip motor, owner was looking to go from 12.5's with a mild 440 to 10.5's...job done, no power adders in our NSS class....only downside is its on its last bore (4.565) but the rpm we push it to it should last.

We got a guy here who races a 3900lb Challenger with the same type 580 motor, same heads but its good spec, 12.5:1 750 roller, twin Doms etc. makes around 890hp, runs 9.6's, put that in a 2800 A-bod and it'll go 8.50's, some like to do it the hard way.
