Hopefully not off track.
But with things the way they are today, would this be a 'blueprint' operation to consider?
Most know how this works.
You have pistons in hand before final hone.
You have main bearings in place and measured before grinding crank.
You get the idea.
Disclaimer. I dont have a lot of real world experience, but being a machinist I think about this shtuff.
For sake of discussion lets assume we have good quality parts and machine work is accurate.
Numbers/design are just for theory only.
So picture this. We have a lifter on cam.
Left side of lifter is in line with cam lobe.
Cam lobe tapers .010 down to right.
Lifter has crown of .005
You guys with parts in hand could give an idea on real world numbers.
So now we have cam company A that has these dimensions.
Now some prefer to mix and match companys.
So company B's lifters have .003 crown.
Installed on A's cam you lose .002.
Would this be a case where one would want to have the cam in hand and grind lifters to 'match'?
I know brand and breed of engine design comes into play.
And level of build also. IE. Backyard build vs. Nascar build.
Whats your experience or opinion on the matter?
