Well-Known Member 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.
