363 how crazy am I Cobra intake

Time to build a motor (95% DD 5% track) Will build over the winter
Dart 363 Don't care about high RPMs just want to max out the intake yield. idel-1,500 to 5,300-5,800rpms
11r heads (190 or 205??)
93 obtain (9.5-1 or 10.5-1??) Run NO2 on kit say 125-250 shot.
1 3/4 shorties and 3in out the back
T5
Nitrous plate between the upper and lower

I know its crazy but this is a 93 cobra and I just want no matter what change for the 93 cobra intake. Now it has been ported by Tmoss all info says that puts it at 270 cfms. It has a 1250 port the BUT heads are 1262.
Should I open it on up? (I emailed Tmoss he said I could send it back and open #1 and #5 up and port match)
But from what I've read I will still be at 270 cfms due to the upper (am I wrong?) If so ((I)) could just port mach it and call it a day.

Have 65mm Tb all my reading says that puts me at 664 cfms
Will be a custom cam built for the build

I have been reading for 3 days and everything I have read still doesn't really tell me how much I am giving up due to this just wondering how much HP I am giving up. I have read the flow is about the same as the Edelbrock II with mine being ported.

Or maybe I have The head Flow @.500 300cfms so that 30cfm difference so 30 x 1.78= 53.4 +or- I have seen many 500+ builds so 450hp should me promising on a T5 to the wheels.

From what I have read the 363ci will help pull air in and the right cam will help a ton. From how I see it having a bigger head should make less flow pressure and let more air into the head I would think lack of air being able to get into the head would make it easier pull air in. 1 3/4 with 3in will help keep pressure down also.

I would be very happy with 400-450hp Maybe 125-250 shot 500+hp

I want this motor to be capable of 1000+hp just tamed by the intake and cam. That why I'm thinking 205 heads.

My original build most other info on first post.

Any advice say I'm crazy give me your 2 cents. Maybe I can make a dollar.

Update 5/15/19 will have motor at the end of the month

Thought I would post my engine build (Fordstroker built)

I'm hoping for 500HP NA but I built this motor for 1,200hp+.

Dart SHP 363 Internal Balanced, Trickflow 11R 205 heads 66cc (Fel Pro MLS 1134 Head Gaskets). 10.1 compression
RPM 4340 crank, Scat 4340 H Beam Rods, 2618 Forged Wiseco Pistons, Wiseco's GFX ring. Motor is good for 9k rpms if I used solid lifters (I'm not).
Custom cam for NA (Idle to 6,500rpms)
8 way adjustable SA Gear billet timing chain with a torrigton bearing
Morel HYD roller link bar lifters. (5323)
7/16 pushrods 4130 Chromemoly
Jesel shaft rockers (They only make one for the 11r heads) (KPS-470191)
Moroso Oil Pan with billet end seals (oil drainback added supercharger or turbo just if I ever want to go that direction)
Melling Standard Volume Oil Pump (10687)(I didn't want a high volume pump)
Moroso Oil Pump Pick up (24516)
ARP Billet Oil Pumpshaft
New timing cover
Edelbrock Water Pump (8840) (He is going to cut the tip down to 3/8 to help fit me electric fan)
All ARP bolts (All of them I know its a little extreme) LMR make a kit for the timing and water pump
All Fel Pro gaskets

I have made 500hp on a 280hp motor for years so this time I went the opposite direction. After some research I seen the shaft rockers were way better especially for a daily driver I want this motor to be good for 200k-300k miles before rebuild.
