I think if you are going for the budget build so to speak which my build cost me $1750 parts/labor from 65hp/78trq to 90hp/100trq i didn't do to bad using a 203 set up.
Just built my engine:
2005 Roadglide
103" Dave Mackie Megasphere Heads
Mackie Megasphere Pistons 10.5to11:1 CR
Woods W8 .590 Cams
Thunderheader 2-1
TTS Tuner Tuned by Barry at KIWI INDAIN PERFORMANCE in Riverside
118Ft Lbs/106HP
Is there a down side to your build? Did you do the labor? Nice numbers. I am kinda new but when you say bored to match your 103 pistons, does that mean that you didnt change the stroke?
I know that the 103 build is expensive thats why I went 95ci.
