340 build
OK here we go.
Years ago .040: was the Minimal clearance for Piston to Head Clearance that you should EVER HAVE! now .035 is comen.
Now i know that .040 was the "Safe" number because there is many many variables that would make a true minimal clearance
Such as Alu rod......would need more clearance
Standard steel rod would need more clearance then a stronger steel aftermarket rod.
Forged piston would need more clearance due to more expansion then Cast piston......
an old Heavy forged piston and stock rod would need more clearance do to extra weight or inertia Which also has to do with RPM
Which brings in another variable, Stroke. the more you have the more clearance you have to have.
Now, we have no idea, how high the previous owner revved this eng,
Now using all of the variables above. the only one that would require more clearance, would be the alu rod (of course) and a stroked eng(more than his 3.31 stroke)
Why did i write all of this?
I find it Very curious that his......OK maybe i wrote all of this for nothing!
I can't believe no one call me on my math mistake, above .053 head gasket -.020 piston pop up is NOT .013":BangHead: It's .033:wtf:
going back to edit previous post.
I was getting real excited about us, being able to have as tight, of a quench as .013":BangHead::BangHead::BangHead:
