Help with 302 beef-up

[Guyver027]

I am gonna swap out my tired '86 5.0 for a '93 5.0 out of a t-bird. I have already done a mass air swap so that shouldn't limit my cam choice too much.
I wanted to put a cam in the motor before swapping, but since a future 351 swap is in the works for the fall... I dont want to spend a lot of money on the 302. I was wondering if an F303 cam would work with a stock long block. Especially in the valve/ piston clearence department. I was figuring If the f303 worked well in the 302 I would throw it in the 351 with a set 1.7 rockers,when the time came...
But if you all say don't bother... or stop being a moron and buy an E-cam for now... well I guess thats what I will have to do...
I have researched this a lot on other forums, and 50% of the people swear the f-cam will work awesome... and 50% say it runs like crap. Or that it just plain wont work and the valves will hit... My experience is that a good percentage of people dont know their ass from their elbow, probably have never even owned a mustang let alone built one, and are only blowing smoke up everyone elses ass... So I figued I'd do the most logical thing and ask the question myself...
Anyone have any helpfull suggestions or input let me know... It will be greatly appreciated..
