The thing is; your 284/296/110 cam doesn't actually close the valves where you might think, either. The advertised numbers are usually taken at .008 tappet lift, or Comps are usually at .006 tappet lift. But the actual on-the-seat and not-leaking points can be waaay on down the line.
Perhaps(I'm guessing) even 15 degrees on down the line at each end making your 284/296 into a true 314/326/110..
Also;FYI; if you have a 110LSA cam installed at 106, then it is 4* advanced. The advance may have been ground into the cam and so perhaps it fell in at 106 with no additional fudging, but none-the-less, in at 106 is 4* advanced, on a 110LSA cam. Jus saying.
If the above cam makes at least 155psi cranking cylinder pressure, then it will be fairly peppy with a true 2450 stall TC;but I don't think any 79 TC is gonna work.
If the car has 3.23s or less;you will come to dislike those intensely, because the power doesn't wake up until around 4800 rpm, which in first gear with 3.23s, is ~ 46 mph. So install some skinny tires and let her rip.
And also if the pressure is significantly less than 150,then you might find the bottom-end soft. A true 10.2/1 Scr is about right for that Comp 284/296/110cam.
That's a pretty big street cam for a 17 yearold. Getting sideways at 40+ mph when the cam hits, can lead to catastrophic results. Put some 4.30s in there and the power will hit around 30/35, then some 295s so he can brake while going sideways, then a hidden rev-limiter........ jus saying,lol.
