I know ! Another cam selection post

The below combo is close to what you are wanting and it ran in the high 12's with the MPH of a mid 12 car


Here's what I had in the early 90's. Won many a street race with this combo in Escondido Ca. back in the day.
1972 340 Duster 3 speed manual brakes, manual steering car. pulled tired 340 out and sold it for $500 dollars which is what I paid for the car. Built the following engine for it:
74 360 .030 over
Badger 9 to 1 pistons
stock 360 crank .010 mains and .010 rods
MP 274-474 lift cam
home ported J heads with 2.02 and 1.60 valves
MP dual plane intake and Holley 3310-1 780 vacuum secondary carb.
hooker 1 3/4 super comp headers and 2 1/2 dual exhaust to 40 series mufflers turned down before the axle
833 4 speed, Hayes center force clutch and pressure plate.
original 340 flywheel drilled for balance as per the MP bible performance book
8 3/4 with 3.91 gears and sure grip.
26 x 10 slicks
This combo was good for 12.80's at 107-108 mph spinning the slicks at the world famous Carlsbad drag strip back in the early 90's. They did not have 60 foot timing lights back in the day and you were lucky to get reaction time on your time slip. Sadly this drag strip closed in the late 90's or early 2000's to make room for a business park. Those were the days had a lot of fun with that car. It was known in Escondido as Al Bundy's car from "Married with Children" As a side note the short block is still together and in my 74 Challenger slightly detuned, but it is very tired and will be coming out when I get the car back from paint and body hopefully the first part of the new year.
