    Pickup interference above 4.15, if you use Mopar rods. Use a crank with 2.2 rod journals for BBC rods, 4 3/8 fits.
    I'm building a 440 based 522, 4 3/8 crank, 7.1 rat rods, Ross pistons.

      I'm definitely going to have to dig around the 440 source site now. I mean that's a long arm there. Can you say 500 ft lb at 2500 rpm? :eek:

      I'd also price line boring block and fitting caps to fit a stock 440 crank if you've already got one.
      At least worth considering.

        37's and a rear D60 with enough power for a 4wd burnout? Might want to rethink that rear D60, get a cheap 14BFF instead, that 60 won't last if that's the abuse it sees. (Also a Jeep guy here, broken many axles)

          Yep, I'd have to agree 440 source is the lowest cost. There are a few other options size wise available. 451 is a great choice.

          Mopar Muscle did some comprehensive testing...& porting.... on the BB production heads. I still have the magazines. From what I recall, once ported they were all pretty close in flow #s.

          Yeah the problem is I know Jack about real head porting. Beyond mild bowl blending and maybe a little port matching I'd get out of my depth real quick

          Lowest cost stroker 426 ci. would be offset grinding a 383 crank to bbc rod journals, use a 6.70 connecting rod & 1.485 compression height Pistons from 440 source That would put your piston .015 under deck & leave it
          If you wanted to step up to a bigger cubic inch later add a 3.915 stroke crank to make a 470.
          Just a thought, or offset a 440 crank to bbc and same rod, just use a 1.32 ch piston
