I'm installing this set up this weekend and wanted to see what kind of a gain I will get. I have LPE stage 3 heads that flow tested at 320 and a 228/232 duration .588/.595 Valve lift 114 Lobe for cam. I hope it's not a watse of money!

 

With your mods you should see good gains. With a tune I would say 25rwhp would be about right.

 

10-15rwhp
