Hey by chance could we see your dyno sheet? Also are you running a stock length R intake or modded intake runner length? I was wondering if the 23x duration would carry the stock intake to 6500rpm peak. It seems the stock intake runner length along with stock 212 duration cams brings peak in at around 5700-6 but the lift helps hold the power. What are the other mods if you don't mind me asking?
Thanks ahead of time
