gt40x power increase and Q's ?

[Jay5_o]

couple of Question's, lost interest in my mustang for last couple years,got into jeep offroading, but gaining interest again and doing a rebuild on 5.0, started refreshining the bottom end with rings and bearings , also ordered gt40x "turbo swirl" heads, e-303 cam, cobra intake manifold, 70mm throttle body.

what kind of hp and tq gains can i expect with this build ? equals to a 100 shot of NOS i hope?

will my factory valve covers and bbk shorties work on these gt40x heads ?

If stang runs fine on SD i will leave it other wise i will conver to mass air , what size of injectors should i get with this combo with 100hp shot of laughing gas?

thanks for any help

I have a similar set up with mass air and have no problems, minus the typical Ecam idle but it isn't that bad. I believe you should be able to use your same manifold covers and yes the shorties will work. I have 30lb injectors and probably should have purchased the 24's instead but i am not running nitrous.
