block thickness (cylinder walls)

guy's what is a good block thickness all the way around. just got 2 blocks tested and the guy's testing it know 0 (ZREO) about FORD's. I have one that is standard and a local looking to buy it but was not sure what to tell him or show. are the thrust side more important than the non thrust side?

The non thrust can be much thinner than the major thrust side....just like the minor side can be some thinner than the major side. I'm not sure what you could tell/show him about checking the block...he knows how to do it or he does not.

what is the thinest that you would run a block to on each side?

The only thing I'd say for sure is it'd depend a lot on the appplication.  I will not offer an opinion being that most of my experience is with the A460 block.

I just wrote a reply for this thread, a "BOOK" if you will, covering details about all kinds of criteria to be considered, from FoMoCo block history back to the 1960's, to stroker build history back to the 1980's, to details about wall thickness and what should be evaluated/what is considered allowable, to factors outside of sonic checking that should also be considered when determining allowable wall thickness for a given build, to block material, to sonic checking techniques, to real-world experiences relative to wall thickness via examples of several builders, a bulleted summarization, etc.

I then clicked "Preview" and had to log in again, at which point my hours of writing vaporized.

Write it again on a spread sheet and paste it over when your done.

the first time was just practice.

And save it! Also, select the entire text and hit Ctrl C. This copies the selection to the clipboard. and you can do a Ctrl V to paste it into a reply box.

well Paul i'm so sorry this has happened because i would have read the whole thing. All I'm wanting to know is what some may consider then minimum thickness.

NORMALLY with an OEM production 429/460 block you would like to see at least .150" to .250" AFTER it is finished.

Does this apply to both thrust and non-thrust? Adjacent to the wrist pin? I realize everone with knowledge has varying opinions on this.

imo,it wouldn't really matter if he doesn't know Fords. If he knows anything about building engines and "Thrust/Non Thrust",Ford,Chevy,etc. wouldn't really make a difference.Like lem said,the HP and Application of the build would be the determining factor more than Block brand.

what type(mix) of iron also plays a role on wall strenght

I've heard of some block with just .100 and a half fill living

The "thin-ist" section of my block rings .113", cant remember which hole, or where on the hole. 'course when you're only makin 229.3 Hp, it's good....wooo hoooo.!.
