I have a 1993 cobra and im looking to put a f-303 cam and i was wondering what all i have to change when it comes to mass air flow and map air flow and to see if ther will be any problem with the valves hitting the pistons or anything thats a real big mechanical problem......

PX429

what else is modded on the car?

it has shorty headers offroad h pipe and flow master super 40s it also has a 75 mm bbk throttle body and 373 gears

why? the fcam is a ok cam but there are so many better ones for similar price. please reconsider. and as far as ptv issues the 5.0 is good until somewhere around 560 lift. the trick flow stage 2 cam is usually the biggest cam u can get in a stock 5.0.

what would you prefer as a cam the car actually is a 1988 gt mustang with a 93 cobra motor with all th mods above

anythin but, haveu looked at comp cams, trick flow (yea i said it) and or maybe even a x303 cam? the 5.0 is the 350 chevy of fords, there are a thousand parts out there for it u just have to do a little lookin.

ok i have one more question a friend of mine actually has a z-303 sitting in his bedroom and just sitting not being used and its brand new would i have any valve to piston problems

thats funny i was thinkin about this cam a while ago, i was told that u might have ptv issues, but the trick flow stage 2 cam is a little bigger and there have been many accounts of that being used on a stock block, so i would assume it would fit, but please tell him to check the ptv. the cam itself is really unknown, i have not heard of it being used, people usually go for the x cam, but i would imagine that the z would make good power especially wit gt40 heads. but thats jmo.
