    Ok I'm debating on building this 5.7 stroked to a 394 with a kit from MMX. It's a 2014 block with stock eagle heads and will be carbureted. Just curious what power output you think it will make. Intake I was thinking of the OCP dual plane. Thinking of building for my GTX because I sold Dart I was going to put it in. Currently I have a 440 in my 69 GTX with a 4 speed dana 60 and 4.10 gears. If not building this was thinking of doing a 440 with some trick flow heads. Here is the cam specs for the Hemi.

    I have a 6.1 based 426, very street friendly cam, ported intake with larger throttle body , headers and some head work running the stock computer. It made 589 on the dyno but it needs some tuning work. Basically a lot will depend on your cam choice but 500hp probably isn’t unrealistic. Arrington posts dyno results of various (Fuel injected) combinations.

      I'm thinking at least 550 hp and 500 plus torque. Kind of debating if I will like it over the 440 in it now. It's right 400hp and 490tq.
