Yes I'm running the eaton m112...its been stage 3 ported and pullied, shootin for 500rwhp until I can upgrade to a whiple or Kenny bell. Ya the 331 plate is because of my first plans for the car...I had a 331 stroker sbf pushrod set up i made mounts,drive line, almost done except for the dry sump oil system i was gonna do due to the Clearence issues of the oil pump and rack/pinion. I gotta get the plate changed

I do have a dohc 5.4 swap in my 01 mustang
