Valve Clearance on Larger Camshaft and Flat Top Pistons
It sounds like what your saying is that the information in my response is " dead wrong". Maybe, but the responses I quoted are direct quotes from Billy Godbold's new book on camshafts. In the section titled "checking undeflected and deflected lift". It's possible you are right and those quotes are errors in his book. I still recommend reading it.
Pay attention because I’m typing very slooooooooooow so you can possibly grasp the concept.
I never EVER said the valve train doesn’t flex. I’m betting all I have I’ve fucked with more engines with more spring pressure than you ever have.
I can tell you the pushrod is the single most overlooked component in the engine. I see guys building engines with pushrods too small for a SFT cam and I see the results.
I had an engine on the dyno, a BMM 471 built by some other dude and the moron used a 5/16 pushrod. With just a SFT cam.
After a few warmups and pulls on the dyno that 5/16 pushrod was bending so far that it was rubbing the tunnel. It left a CLEAR witness mark. Do you how big the pushrod tunnel is on a TF 240 head? It’s HUGE and the pushrods were bending that much.
And yet, they didn’t stay bent.
Now what YOU want ME to believe is that you are so stupid you can’t grasp the concept of bending loads and plastic deformation. If you don’t know what that is LOOK IT UP because that’s what you want me to believe.
When you are turning an engine BY ******* HAD if the pushrod does deflect and that’s a giant IF by the way, that it STAYS BENT when you stop turning it.
Do you want me to think you are that thick? That dull? You are leaving me no choice to not think otherwise.
I’ll say it one more time.
If you turn the engine by hand and the pushrod bends, and you STOP TURNING IT the pushrod is no longer BENT.
If it was you’d need to replace the pushrod
You know exactly what I’m saying. You get it. But you want to continue on, trying to goad me into something. That’s grade school ****. I’m now leaning towards he fact that is your education and maturity level.
Go read the Godbold book and post the page number where Billy says that while checking cam timing the pushrods bend and stay bent when you stop turning the engine over.
Again, you are DEAD WRONG. Shame on you for putting bullshit like this out for the world to read.
