i have a d24 block already bored .060, can i take it to .080 safely?

Take it to a machine shop that can sonic test it. They can determine if it's thick enough to stand that much overbore.

Sleeves are not actually that expensive, I was surprised!

Bore-press in sleeves, hone to std. maybe overbore sizes are avail.

I believe  good/reasonably priced parts are avail. at Terrel Machine-Texas

Think there is a link to them in the Resources tab- then suppliers

 

Good luck

+1 on this advice.  We sonic-tested my 230 block, 4 shots each at the top, middle and bottom of each bore.  I had LOTS of metal in all locations.  Because of the particular rings and pistons we used, mine wound up at 0.072" oversize.
