That is mild

I'm running a 230/236 solid in a 390 with power brakes and a 3.7 4 speed. Mine is on a 108 lobe center and has a tight lash setting of 12 thou so it runs a little bigger than somehting set up for a typical 21 or 22 thou lash. You have a bunch more cubes and I et that cams lash setting is close to 10 more eating up some of your duration. Scott at Camresearch ground mine and recomended the tighter lobe center to narrow the tourque curve building more torque early. I am really happy with the way it runs in my Torino. I'd give him or the guy at Oregon cams a call. Both of those guys are veery into FEs and have several grinds specifically tailored to FEs.
