Default shift points... 224/227 113+3 in a 5.3 with an SS360

I'm about to have my last POS retune done with W4M before getting Charlie to tune me up in a month or two... anyway... I need to get some good shift points in this thing. the cam is a 224/227 113+3 in a 5.3 with a Yank SS3600 converter, FLT-5 trans, and 4.10's in an ecsb... I am thinking about:

1-2 6500
2-3 6300
3-4 6200

the problem is, I havent ran this cam enough to really figure out where it stops pulling. I just know the power really comes on at about 31-3200 RPM...
-I just hope the m-f'er gets my damn speedo straight

I think your estimates will do fine. Like I said earlier, I would run a bit more conservative since you're over 100k mi and stock rod bolts. JMHO.

1-2 6400
2-3 6200

With half a negative .50* of overlap I would go ahead and say spin it to the shift points that you noted. They should be fine.

Me three, I would not recommend much 3-4 shifting though, might put that at 6500 or so.
