Default E303 cam with stock heads?

I was supposed to go work on my 94 gt 5.0 today. my garadge has no power so i am putting it off for another week... I am upgrading basically every bolt on. but heads.. I would like to upgrade to a e303 cam but i was not shure if that would be ok consitering I am still running stock heads. If anyone could let me know I would greatly appreciate it..I have the front of the car apaet now and if i can i should just put the cam in now while its all out! thanks again guys!

The cam will work with your heads, but it wont make power to its fullest potential.

What other mods do you have? Unless you have all the basics, id hold out on a cam.

I have basically everything upgraded but the heads and the block. the whole induction system is done, ignition system is done, fuel , suspension, braking.. basically the whole car is done but the cam and the heads and the internal engine parts.. the engine runs strong and i am going to upgrade the heads and the block next winter but id like to upgrade the cam for at least this summer! do u think this will be ok?

youll gain hp from it but with stock heads the cam will never hit its full potential. the stock heads just dont flow enough

it would be a good idea to put in new valve springs on those stock heads

Don't waste money getting a cam if you are not going to get a diff set of heads. You will really be kicking yourself in the *** for it.

You did a really good job of listing your mods. Theres probably at least 8 variations of any 5.0 part you could imagine. You need to be more specific.

I dont see why he'd kick himself in the **** for putting a cam in, because its not like he has to pull the heads to get at the cam. The cam will be there when he puts his heads on.

My friend has headers back exhaust and a fms e303 cam and it rips pretty hard. I would suggest getting if for now, you will see and feel an hp gain, but when you get your heads it will be even better.
