Re: X1 cam an milled heads. Ya thanks alot MTI Did the specify a certain gasket? that could very well be the problem. Or was the cam degreed correctly when it was put in?

Re: X1 cam an milled heads. Ya thanks alot MTI Do you have aftermarket heads? If so they might have been milled when you got them.

Re: X1 cam an milled heads. Ya thanks alot MTI I thought about this some more. Why didnt you hand crank the motor over by hand to see if there was PV issues. Or even clay it? instead of pointing fingers at MTI? Or could it be some 5.3 heads that were milled .30 additionally? that could easily make the combustion chamber smaller to have PV issues.

Re: X1 cam an milled heads. Ya thanks alot MTI Wow!
My GTP S+ heads and piglet cam looked similar when we opened it up the other day.
We had 78thousandths clearnance and I think my 918 springs just could not keep up.
What springs were you using? Could it have come fomr a combination of low PV clearance AND weak springs?

Re: X1 cam an milled heads. Ya thanks alot MTI Ohh, if I may ask what exactly were your symptoms?
Did you notice a lack of power or was it the noise? etc..

Re: X1 cam an milled heads. Ya thanks alot MTI Did you miss a shift?? When P/V is close, a mis-shift (and the resulting mechanical over-rev) can easily result in a bit of valve float (I would find this pretty believable, as one piston looks like it was smacked a LOT harder than the others in the pics).
Additionally, were your heads flat milled, or angle milled, do you know?? Angle milling slightly re-orients the face of the valve to the face of the piston... could create an interference problem.
Just throwing out some ideas...

Re: X1 cam an milled heads. Ya thanks alot MTI Make it a point to ALWAYS check piston to valve clearance whatever combination you have. Don't take anybodys word for it. Just too many variables. I like to see .080-.090" minimum.

Re: X1 cam an milled heads. Ya thanks alot MTI Whoa, whoa, whoa, big guy.
There is a lot of bullets in the air and not a lot of info.
What springs were being used? 918's are simply not "ideal" for that cam.
Now 350 pounds at open would be a good setup...how strong were YOUR springs?
Did you ever miss a shift and over rev that hot rod?
MTI has installed MANY (way over a 100) X1 cams in a H/C- MTI stage2 .030 milled 346 set up. Were nary a problem.
We dont know squat about your heads, springs, race history of the motor, machine work, etc.
I can assure you that there are MANY folks running a MTI stage 2 head/X1 cam set up with zero piston to valve problems.
Sorry you had your mishap... but I cannot at this place in time point definitively at MTI and say "It's their fault".
You should ALWAYS put a dab of clay in there, some old gaskets (or somesuch) and check PV clearance.... ALWAYS. ALWAYS degree in your cam...ALWAYS.
Again sorry you had a prob.

Re: X1 cam an milled heads. Ya thanks alot MTI Whoa!! This is crazy. I am with John on this "There is a lot of bullets in the air and not a lot of info"
You guys are kind of been a little hard on him for NO reason. He did not bash MTI, he just said that they gave him the wrong info.
We might need to hear the WHOLE story before we start saying that the guy F**Ked up.
I am not saying that MTI is at fault, but if they told him that it would clear no matter what then THEY ARE AT FAULT!

Re: X1 cam an milled heads. Ya thanks alot MTI I disagree but whatever.
Anyone that has been putting together hot rods for any length of time knows you can never just assume because one person says it's ok that it is. I am going through the same problem as him but I am not going to blame GTP or anyone else. Sometimes **** just doesntwork out for one reason or other. Man up and fix it I say.
Now if MTI built it and refused to fix it then they are at fault no matter what.
Just my view on things....

Re: X1 cam an milled heads. Ya thanks alot MTI If MTI is at fault they would fix the issue. I know this for a fact!
Next- I have the X1 cam and stage 2 heads. You need double springs. This cam likes to go high! But there are many factors in problems like yourself! I understand your anger, thats why I payed for someone to put my car together. Helps take the mistakes out. This cam is awsome and I recommend it to anyone. MTI has taken car of me and many of it`s people. Good Luck! Talk to Jayson , he is really a good guy!

Re: X1 cam an milled heads. Ya thanks alot MTI Well guy's I know I should have checked everything better. I was kinda a blind follower of MTI.
When I recieved My X1 cam the specs were way off.
and I started this post.
https://ls1tech.com/ubb/cgi-bin/ulti...=011134#000005
But I was asured everything was OK.
So I installed it. Then I had a bad lifter. So I went ahead and got the heads done. I talked to MTI a few times about it. And they Told me they take .30 off all the time with this cam, as part of there stage 2 package. They are 5.7 heads. Stock gaskets, and Rev springs
I wasnt looking to Bash MTI. The car hasnt been race with the heads on. And I didnt miss anyshifts.
I just wanted to post pics for the other Blind Faithfull out there. I never expected MTI to do anything about this. Im installing Diamond pistons right now to fix the problem

Well, since they're the ones that did your heads and they felt confident that the X1 (which is their own cam) would have clearance even based on your cam card - I'd say there's a little bit of responsibility on them there.
I went through this a little myself because I had this cam in my car w/ ported LS6 heads from Absolute. Jay personally checked the clearance for me with the heads he did and this cam. I know he checked what others were porting their heads at w/ this cam and I remember him telling me the clearance was too close at .30 thousandths with LS6 heads especially.
Even though MTI said it would be fine, you have to check the clearance no matter what if you're doing your own work. If they did the install, I would say it's their responsibility 100% for the error, but you can't blame them completely if you didn't check it yourself to make sure. I can empathize with you, it sucks for sure. <img border="0" title="" alt="[Frown]" src="gr_sad.gif" />

Re: X1 cam an milled heads. Ya thanks alot MTI just cause it is MTI don't make them perfect. everyone make mistakes. altho MTI is at the top of the list as a great shop <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" /> they are not god. but close <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> . bottom line this is a reminder to check. i joked to MECH about the lift of the cam. i said the valves were screaming in there because they were afraid Mr. piston was going to hit them. now we find out Mr. piston got bitched slapped <img border="0" alt="[punch]" title="" src="graemlins/gr_punch.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
