So the engine details is

* All Pro LS7 intake runner 280cc Chamber 58cc , Intake valve 2.200 , Exhaust 1.600 , Springs 900lift
*Mast LS7 EFI 4500 intake with accufab 4500 throttle
*Solid roller 27x\28x 8xx\8xx 114
Fuel details
* 60lbs injectors , Fast fuel rails
* Aermotive 340 fuel pump in tank
The car will runs C16 N/A and C16 with the spray through stand alone fuel system , Will install Wilson 4500 2 stage plate system

Add a dry sump with some good scavenge stages or a vac. pump and let her eat. On motor 720-730rwhp SAE at least is what I would expect if that my was setup.

Since you're spraying this engine I would've gone with the larger intake runner that All Pro makes.

A nitrous build engine... is not the top HP producer N-A, IMO, and i would keep stroke to 4.00", however who cares that your rings are 0.08 wider, if you want it for comp.
Where you place the shifting points in the design of your cam will dictate your power making ability N-A. For NOS you'll need a 115 lsa or so, again somewhat detracting from your N-A meet range, but hey, 250 shot will have the answer. I will definitely have Patrick G design the cam for the one shot to the top solution, unless you want to try 3 or 4 different cams in quest for the good one. Camhelp@gerragroup.com for $25 bucks is the best deal in high performance today, he will else direct you on the correct parts for the job, so is best to contact him before you start expending, so you just buy it all, ones, i know i gave you info you did not request, but hey, the wise will appreciate it, yeah I'll take a shot, i say meet 740/750whp N-A is in the window. I think for a good shot, compression in 12.00 to 1 is optimal, and still, before you start the new motor have the strongest starter you can get your hands on, cause your stock one will not do, as will take a lil longer to start [in the case of ECM tuning] causing extra fuel injected at start trowing off, the work of your tuner, in every attempt, good luck with your build, take your time do it rite, do it ones....

But do you think with my setup and kooks 2 inch headers and nitrous 300HP will runs good ?
YES. It will run in the 8's fairly easy. The larger port would work better with much more nitrous then that.
