        1971 Plymouth Duster in stock dress.
        I used to run an LA 360 stock low compression short block from a 77 truck. Stock x heads with a good valve job. Comp cams .525 lift solid lifter camshaft. Torker 2 intake with 750 DP. 1 5/8 cheap headers. 2 1/2” exhaust with turn downs at axle. Turbo Action 10” 3800 stall converter. 727 with reverse Manual valve body. 4.30 gears. Weld wheels running M&H Racemaster J60 15’s on the rear. Ran 12.51 @ 107 and some change.
        I still have the car but will be running a 360 magnum that duplicates the 380 crate engine.

            I bet the converter alone could get you in the 11.80s or so.

            @Scamper

            You are using CalTracs with Super stock springs ?
            How is that working out for you ?
            Seems to be a complete oxymoron with that set up, no ?
            Thanks.

            I called Caltracs and they said no problem actually the cuda guy there said he runs the same. They work very well solved a lot of traction issues
