Ptv ?
So i got a fti ssht cam , 228/232 .612/.600 111+3 lsa
its going on my lq4 with my heads being milled .050, do you guys thunk i'll run into ptv problems ! I know the best thing is to clay the pistons, but just would like ya'll opinion ! |
be close but like you said clay is the best way. we should roll race before and after to see the results
|
I'm down for that send me that video that alex told me about! n-e ways spoke to richard at wcch's a few days ago and he told me it would be perty close but should clear , I really want it to clear cuz I really like the specs on that cam and have heard good things about it!
|
I'm not even going to guess without you doing a clay imprint... that's a pretty big lift for heads that are shaved that much.
I am very interested to see this run though :hmmm: |
I would think your getting close with them specs, like said clay them.. Can I ask why you went so donkey dick on that cam??? Stock valves or bigger on intake and exhaust???
|
I have never clayed for PVC. Assemble everything like you would, and turn the engine over by hand. When you get to the clearance areas use a pry bar, and pry down on the rocker/valve assembly. Give it at least .060 clearance, and you should be fine. The clay just takes one more step and a lot more work, you will be fine with the pry bar.

Jonh : I'm still trying to figure that out my self , i'm actually considering getting rid of it but might just try it to ! I was actually spect out by a known cam guru at more duration on the intake but only a 600 lift ,and after doing intense research on cams and seing this 1 for sell i thought it was the cam 4 me , but then started thinking about ptv !
Gadgetized: Thank for the help i did not think off that but will try it , i'm not trying to pull the heads off unless nothing else can be done! |
And after thinking of it, I am not sure how the clay would work with hydraulic liters without measuring.
