383 or 440 Dilema

Here Are The Specs Of The 440 That I was going to use Before The 383 Turned up

480 Hp. Bored 30th, Trw 11.5-1 Forged Pistons. Crank Grouns .010 shotpeened LY rods , ARP bolts Balanced Rotating assembly, Hi Vol Oil pump, Moly Drive, Crane Camshaft 512 246@ 50, Rhoades Lifters, 915 Heads Closed Chamber Ported, Stainless Valves 2.14 Inlet, 1.81 Exhaust HD springs retaiiners etc. May Need Rings And Bearings,

My Concern Is 11.5-1 on Pump Gas,

The 383 I bought with a Trans and other Bits, looked to clean for a Rebuilder , IT may have been built years but all the parts seemed newish , Pulled the Pan off the bearings were near perfect looked up and the pistons were aftermarket crank seemed mint and timing chain hadnt much play , it also had a newish fuel pump , new holley dominator manifold etc , Dont Know what the Specs are But Its Probably Not Much More Than Stock,

Some body said earlier that the 440 was the Flagship from Ma Mopar But that was 40 odd years ago,

Thanks For all the Responses It Great But I not holding anybody Responsible , You input is more than Welcome At the End of the Day I will take the info I need and Run with it

Front end Weight and drive ability is a Key ingredient to which motor I use , With Either motor I will be looking at alloy heads, Glass Bonnet, Electric waterpump , Glass Bumper etc

All I want Is A street able Car That Would run low 12s high 11s

Would the 383 do this??? I know the 440 has ran 12.3 in a 300kg Heavier A Body
