I was doing some calculations and some measurements last night. Are most valve releifs on aftermarket pistons sized at .508 inch depth. The way we clayed the motor i had in there currently it shows that i have approx .0180 inch of room available even though the piston is slighly above the GE block which is .0018 of inch.

So i figure i have plenty of room to run the oversized ferrea valves on a Wiseco piston from larry.

even on my older JE piston the valve relief was cut .508 is this std thing that all manufacture adhere to.

 

what exactly is the question? i didnt see a single question mark in your entire statement. however i say je 8.8 + eagle rod

 

Well, the literature that came with my Wiseco pistons I just received said they oversize the valve reliefs on all of their pistons to accomadate slightly oversized valve heads. Sorry no specs, but I thought I'd share.

(This JE piston/Eagle rod thing is getting VERY tiresome )

this eagle rod and je piston **** is getting out of hand.

 

I am at a slight loss but want to help with your question, but first what measurement if .508" inch, no way that is the relief depth on any pistons I have seen, that is over one centimeter. thanks to explain, p.s. there is a piston to valve clearance that you should respect, I know you are trying to maximize the proximity of valve to piston - or max valve lift, but you can get more flow by maximizing the airflow at lower lift by getting a cam made that will maintain that.

 

Why don't you be really different and get Eagle pistons and JE rods ?

 

Viren said it right:

Im getting tired of it as well, funny at first but no so funny afterwards.

damn straight this getting out hand. this stupid now...

 

I agree. The Eagle rod je piston was funny at first but now everyone says it. I even took it out of my sig so lets get back to tech. I dont mind the joking around everyonce and a while, but dont kill the joke to death.

can you answer my question re 0.508" relief depth?
