f cam

[mustang112]

has anyone had any problems with the f cam? im going to be buyint my whole rotating assembly here soon and i want to make sure that no one else has had piston to valve issues. im going to measure it when i get it but i want a litte heads up before i buy it all. thanks, adam :)

What heads are you running? Stock piston's? You should be fine though.

[mustang112]

i got a set of gt40p's off steves lx and im running the stock pistons because they are forged. thanks black90lx

I'de use the stock ratio rockers because if you use the higher ratio rockers you might run into piston to valve clearance issues unless you flycut the pistons but i dont know if you'de have to or not

[juiced347]

I'm pretty sure the pistons will need flycut

[black90lx]

What year is the block? You should be fine, i don't see you having any trouble at all. There is alot of people that run the combo you are. I have seen people run a x cam on a stock short block without fly cutting the piston's and that was with victor jr and twisted wedge head's.

[black90lx]

Are the piston's flat or do they have valve reliefs in them?

[mustang112]

they have the valve releifs, its an 88 gt and i am using the same rocker ratio. id love to run the x cam but it seems to risky lol

evil666stang had to flycut his with a fcam and windsor sr heads

evil666stang had to flycut his with a fcam and windsor sr heads

That's because of the 2,02 valves. I ran an f cam with gt40 heads with 1.7 rockers

[black90lx]

There will be no problem at all. go for it

[jack90gt]

I run a x-cam with ported,polished,shaved 40thousands e-7 heads, 1.6 scorpian rr's and no probs at all

[mustang112]

so i can probably run the x cam in it? or would i have to have anything else done to the pistons, heads or change my rocker ratio? thanks again guys, this is really gunna help before i order it

[jack90gt]

I just put mine in and checked ptv clearance and it was fine...I put 600' springs in it too...Just make sure you check ptv to be on safe side though..I still have stock pistons in mine just 30 over is all..I started with stock rockers and just put the new 1.6's on it yesterday..

[mustang112]

ok thanks man. that helps alot... i just looked at a bunch of videos and looked up some info on the x cam and it sounds like a lot better cam then the f cam. duration is a little shorter but oh well lol. the heads i have have performance beehive springs but idk they are rated at...

[mustang112]

oh yeah and the roller rockers i am using are Competition Cams Ultra-Gold series

[jack90gt]

I went to a 600 lift spring just to be safe in case i wanted to go bigger later on...As the x cam is 542' lift so i have room to play...Good rockers you got there also...I have the cheap scorpian 1.6's but they work

[mustang112]

i dont have the rockers yet but im buying them within the next week or so. im getting my cam, push rods, whole engine gasket set,oil pump,timing chain and gears, roller lifters, roller rockers, piston rings and rods and its going to run me around 1150-1200 shipped. i got the money in the the credit union at my church but the new year and everything they are closed so i have to wait lol.

[jack90gt]

Sounds like it should be pretty nice when you get it done...What car is it in? Mine is a junk slow 89gt aod.....Sucks you have to wait though....Oh well good things come to those who wait

[mustang112]

thanks, its an 88 gt 5spd. ive noticed alot of guys running the aod. mines just for weekend and strip so im sticking with the 5spd. my daily driver is a 98 v6 auto. for when i get stuck in traffic or something and dont want to mess with it lol

[jack90gt]

Haha sounds cool man....

[mustang112]

yeah thanks

[mustang112]

i got the x-cam today. also got my roller rockers and ordered everything else for my rotating assembly besides my crank.
