so im gonna cam, stall, and spray my 4.8. I'm picking up the nos kit this weekend. how big of a cam can i run without changing valve springs, or should i just change them anyways. Kinda looking to run somewhere around a 220/220 cam and a 2500 stall.

 

Springs are based on lift not so much duration. I would put good springs in there if you plan on making any power.

 

Don't waste your money on a 2500, go ahead with the 3200!!! You will be glad you did.

 

Anyhow I would run better springs if your planning on spraying.

 

should i run a plate or just run a nozzle

 

Plates work much better than nozzle, I love my N2Outlet plate. Also, I have a Yank SS3600 converter I can hook you up with if interested. Also, do pushrods and springs and not too large of a cam. 220/220 should be fine. I would try to keep it under .600 lift no matter what cam you choose. and a 113 LSA seems to do the trick on the spray.

 

Yes do springs stall 3200+
