That is VERY impressive bro., although when I look at your cam Its no wonder I would LOVE to hear that moter sing! I just put a baby cam in mine,....(228/232.......112 ) cause I do a lot of "long rider".....(old school) and STILL I was amazed with what I wound up with Ive got just a "little"
over 400 r.w.h.p. and when I want to she literally jumps up and screems.

How many rpms are you spinning her out to ?? Seems like you should make a little more power considering you have 415 ci's. You have good heads, cam, and a free flowing exhaust. The pro series would have yielded a couple more but thats' trivial. The street series headers are good too. Seems like you should make power all the way to almost 7 grand.
Good numbers though, and have fun with all that torque.

Congrats...those are very impressive numbers. I'm still on the fence for a FAST 90 set up. Every time I'm ready to order, my tuner tells me the improvement will be vey little due to a small cam (224/581 112LSA) and not worth the expense for parts, labor and tuning. They claim only about a 8-10 rwhp/rwtq gain with a ported FAST 90 and ported LS 90 tb. I thinking about going with a more aggressive cam and lighter springs. I want to get to 475rwhp/450rwtq

Your lift could be increased a bit, and your duration increased more and you will have the power you are looking for. The bigger the cam you go, the more often you will be changing out your valve springs. Big cams do have their draw backs.
