Thread: Once again the supposed Stroked Out GTX...

yeah...I guess replacing the pushrods and lifters and doing a gasket refresh on the top end would work.

Sounds like it should, but no idea as to why the lifter failed that way. i just ant it to run right now so i can drive it without issue, if funds are good i would like to install the xpz at one point and IS4 heads

Get one of those... Stick it on teh end of the pushrod and see how much lift you get out of the cam....

Thanks i never knew i could do that, where can i get these Harbor Freight?

Lighter, freer revving valvetrain isn't a "waste" of money if you got them at the right price.

Also: stock guides are clearanced to .550". Anything more than that would need to have the guides milled...or have the special install kits like that are offered for the XPZ/Thrasher, etc.

Is there a way to find out what lifters are installed on it? or should i just replace them all with stock ones or LS7 lifters?

are they noisy as hell?

If they are, OE-R's are probably in there.

If they're not noisy, they're either stock or LS7, both are fine to run. Stock lifters will start to collapse under high rpm ( 6700 and up ), but most people dont run that high anyways

Hell if I know...LOL....

Nice thanks. I am assuming i will have to do it for both intake and exhaust?

Yea.. That will tell you exhaust and intake lift.

Check the video out. It does sound like it is cammed due to the sound of it but as I said I don't want to say yes to something unless I have proof.

There should be more videos on my account there.

DEF sounds cammed. And sounds like you have OE-R's in there...that baby is ticking alot

Sounds cammed to me! If anything instead of pulling the whole motor just use our old fashion method and drop the cradle to pull the cam out.

Honestly I have never done it that way, I always liked pulling out the top I use a forklift and it's pretty easy to do. And with the engine out I can get to things way better and pull things apart as well. All aftermarket cams have a name on them don't they?

Correct. Sorry should of been more specific.

Pretty easy to do it that way...but if you can pull it I'd recommend that so you'll have more space to work with and the cam should have the specs of it on it.
