Not gonna happen With that many mods PLUS those huge injectors that are a huge overkill any mail order tune would be only "their best guess " Why in the heck would you install such large injectors on an engine without boost ?? The stock GM 28 LB injectors are good for 500 crank HP There is NO HP advantage to going to larger injectors unless you out grow the stock ones-- 42 LB injectors are made for LS engines wirh boost Your cam hdr engine will run PIG RICH with 42 injectors and run lazy and pig rich--- The only way to know for sure if you have outgrown your injectors is to do some data logging on your Injector Duty cycles----Industry STANDARDS say not to exceed 80* duty cycles---otherwise 42's are costing you HP and NOT adding any at all---
I have run a LS N/A engine wiith 550 crank HP with the stock 28 LB injectors with NO issues
All you are going to get is fouled plugs--black smoke--and a lazy rich engine---
