Worth it to build my 273?

hi, I looked up prices, pistons will cost bout the same, rest of parts cost same, as they're for same family of motor.the 360 is NOT the answer for everything!! you'll need gears and suspension, to get close to 12 sec. back in 72, ran a stock 235/273 , with gears n slicks,headers ran 13.31 it was street drivable. didn't drive on highway though. the chassis gets you E.T, motor gets you MPH. just for information, there is a 235/273 that runs in stock eliminator , it runs 11.70, its NOT drivable on street. mid 13 would be very fast for a 273 like you envision. just food for thought.
