It seems your looking for what you "should" have, if you have not checked it yourself to "Know" what you have and build it accordingly, from my standpoint it appears everyone has "seen" what they have observed firsthand to be somewhere in-between the values mentioned, and considering that many may have been "decked" during a rebuild in the past 30 years it's a moot point from my way of thinking, before anyone orders a single part for a engine build these measurements need to be "Known", factory "stock" specs can and do vary, I believe that's why the term "Blueprinting" is so often used and abused, a "Printed" engine is one built to "It's" specs "As Produced", I may again be wrong because I have never seen a 4.1 from the factory built using a turbo/supercharger/nitros, so unless you have the measurements accurately checked, the parts you choose may add up to a mess, and you would not be the first to do so. Everyone wants an easy answer, but without accuracy, easy can and most likely becomes "Wrong", Take a total of what you got-then make your plan. Or not, maybe it will be ok? maybe not? it's up to you to learn what you are doing or what you are guessing.
