Built this motor for a GTM, still up in the air if I am going single or twin turbo, but at this point I am looking for a base HP/TQ number with the mods below (LOOKING FOR CRANK NUMBERS).......will help me to know the NA power before I start thinking of sizing turbo(s). Thx

2005 5.3 aluminum block L33 with 29K miles (stock block).
Stock 243 heads with upgraded 918 springs
Comp Cam XR269 (216/220 525/532 LSA 114)
New LS9 injectors (I believe 58lbs)
2003 LS6 exahaust manifolds
2003 LS6 intake.
Fast fuel rails
6 speed (not GM, the reason for asking crank and not wheel)
Roughly 4 ft of exhaust, no mufflers.
Stock A/C
No power steering
Tuned for 93 octane

What would you guess the base HP/TQ numbers with these mods would be (LOOKING FOR CRANK NUMBERS)? Thx

Anyone?

Lol, take it to a dyno and run it. But I'll make it easy, twin dryers for sure.

It will be dyno tuned once the turbo(s) are installed. At this point 58LBS injectors are very big for a nearly stock engine. I am planning a mail away tune to get the NA engine close, once the turbo(s) are installed, then I will get a true dyno tune. I am trying to decide on turbo sizes. If the engine is good for 410na then 10PSi will get me about 650hp (slightly above my goal). If it is good for 350hp then I will need more PSI to get to where I want, which will mean a different set up.

Will the engine turn 410hp and high 300's TQ (Crank) in N/A form?

It doesn't matter. Turbos are not chosen because of how much power they can make. Call a specialised turbo shop they will explain it to ya.
