I believe you tend to get into lifter galley bleed issues somewhere over around .380-.390 lobe lift.... generally. I would check with Howards and see if they have any issues reported from customers. (Howards Grinds the TF cams IIRC)

I run a Bullet Hydraulic roller in my 517 and I think the lift at the lobe is .380I-.373E and I have no issues at all with the Crane Lifters and I've turned it 6800-7000 many times. I run 264/268 @.050 and with Big mopar wedges the power you feel on the street is really in the mid lifts. Remember a cam spends most of it's open duration between at least 1/3 lift and 2/3 of peak lift.

If you are really worried about it I would send it back to Howards and have it reground to the 235/240 @ .050 and somewhere around .370 lift, it might cost you 10-15 peak hp and the Peak torque rpm will come in a few hundred RPM sooner, but in a Stroker Mopar I doubt you'll miss it.

If that sounds like a broomstick, I know 110% there's someone here that runs High 10's in a street driven B body with that same grind.
