Before I even consider...
If you compare to comp cams popular xe***h line stock 340 cam is similar to the 250 cam and the one being discussed is in line with the 256 cam far from too large.
Don't know why people seem to think you got to strangle your engine to make torque and add air flow for hp.
Both are basically the same except torque is a partial picture and hp is the full picture of what your engine is capable of. Torque is basically a snap shot of one revolution (close as we can get to no rpm in a running engine) and hp is the power of all those revolutions added up.
So to make torque is the same as hp is air flow. The trick with a street car is to build the widest power band without moving too far from idle unless you love deep gears and high stall.
I got a 380 hp create engine even with it's single plane intake and somewhat large cam and mild CR. It makes strong 2000-6000 with a peak at 5400 rpm. It's a little soft under 2000 rpm but that's cause I'm running at the moment 2.96 gears.
I think sometimes we go over board with caution.
