Set of CNC ported 440source stealth heads, 11:1 compression, MP.557 solid cam, edelbrock victor intake, converter that flashes to at least 4500 and you will rev that sucker to near 7000rpm.
If you're dead set on running stock heads, that will be your biggest bottleneck. Stock mopar heads just don't flow and the cost of getting them ported will quickly equal the price of a set of aftermarket heads. But if iron heads is what it's going to be, I'd be getting some work done on them by Dwayne (moparts member fast68plymouth) of Porter Racing Heads. He's a straight up guy and would be my first stop when working with iron heads.
Thats very close to the 400 in my sons Dart. Stock stroke .030 over 400 with KB flattop pistons and Eddy heads cut for 10.6 comp with the KB pistons. MP .557 cam , Eddy RPM intake , 750 DP and 2" CPPA headers. He only has 3.91's in his Dart but he is shifting it about 6700 as he says it feels like its still pulling up to 6700 and even more. He has run 11.40's @ 117 in his 3550 lb Dart and it runs fine on 92 or 93 pump. That short stroke likes to rev alot more then my 440. Ron
