68 Dart first time out

Rather than start a new thread lets see if I can revive this one. I'm ready to make the car faster. Based on the info below can I tune it up? Is it time for some head porting? Or Do I need a bigger badder enging like Brian just built in Car Craft? Lets put the target on the 11.50et mark, don't need more than that on this car. How much HP needed? I'm open to superchargers, and nitrous:D

Would love to here comments on the car like if the numbers all add up. Do you think the motor and car is are working efficient. Is there some tuning in order. Keep in mind the car is a street/strip combo.

Since I didn't build this engine/car I dug up all the paper work to get the specs. Most all the work was by previous owner kind of a budget stroker. Here is the motor specs based on the receipts given to me.

Motor specs
360 block
eagle 408 stroker kit cast crank "I" beam rods dish pistons -16.9cc
Edlebrock Alum. heads part #ED-60779 bare no porting
Cam Lunati part # 40418 .550/.571 lift 256/[email protected] lift duration
Compression 10.4 based on advertised head 63cc and stroker kit numbers
RPM dual plane intake

Mopar electronic ignition orang box

11" convertor 3000 stall guess
904 trans my guess no special treatment

Dana 60 rear with 4.10 gears sure grip

275-60-15 Drag radials 28" tall

Engine Dyno numbers 461hp at 5600rpm 500tq at 4500 rpm

Car weights about 3400 going down the track with me in it.

Can't really stall up the motor on launch or it will spin the tires
leaving the line at about 1000RPM them hammer it. This will normally keep the rear tires hooked.
