hello Dave- I can say more to help but to verify what you need call Glenn Self racing
580- 924-5866
he has built many of these engines and done alot with them....as many know , boring the 292 .0125 is not advised-but has and can be done- for someone who has done this and can answer detailed questions try making this call.
I have never done this procedure but will do what i mentioned earlier in other Post.
keep us informed what you continue you do-thiese are fun engines
by the way, thru all this ,please share what your project is again..ok?
hope this helps
let me add this-i have been shockingly amazed that a .030 bore is best on a high reving 292....my research with old school concpts is that these cylinder walls keep a better ring seal with a strong wall and too much bore weakens the wall and at high rpm,high CR and high heat due to high CR ,the cylinders distort more-faster Et's with less bore!!!!!! I was shocked to find out that more HP can come from a less bored 292-interesting huh?
but then again......
