sleeving Eliminator Premiere block
I have a very early Eliminator Premiere block and dropped a Ti intake valve which in turn put a major ding in the cylinder wall. To save the block it'll need a sleeve maybe several as the shrapnel got into the other cylinders with several getting deep scratches. This will entail taking it from the current 4.560" to 4.6" and will get close to the max safe bore size.
Is there anything special to know with regard to sleeving one of these blocks?

Re: sleeving Eliminator Premiere block
my favourite motor is my old A460 block that I put all 8 sleeves in ,and I used Darton aluminium A96 sleeves as there all exactly 4.801" that way if I hurt a cylinder, its just matter of boring the sleeve out and putting another one in with no distortion to the adjacent cylinders been working for me for 20 years . and the Darton sleeve are real hard and hardly ever wear and ring seal is great!

Thank you. That is a helluva an idea.

One other question, with eight sleeves is there any issue with water jacket sealing or deck stability. This is for a car that sees a lot of street and road miles.

After some additional investigation and consulting with experts, you know who you are, the sleeve idea does not seem as attractive. The high nickel block material is considered to be just as good as the higher end sleeves, ductile iron etc.. Therefore given the sleeve will be around .080" and the remaining material in the affected cylinder will have to be bored out sufficiently accomodate the sleeve that means I'd end up with a .080" sleeve supprted by another ~.080" of original material at the thinest spot on the minor thrust side of the number one hole. It seems that .160" of solid contiguous block material which gets thicker rapidly both above and below the thin midpoint will be ther stronger choice, though not ideal.
Does anyone have experince with engines with that thin a wall survivng at the 1000-1100 HP level?

I think your over thinking it, if you have one or two holes hurt and want to sleeve them to keep everything at 4.560, do it, its not going to hurt anything. Or even boring to 4.600 is no big deal, it will be fine.CDMBill wrote:After some additional investigation and consulting with experts, you know who you are, the sleeve idea does not seem as attractive.

The .040 you have staying at 4.56 is more than enough to rebuild for the rest of your life baring any catastrophic failure. Same with the 4.600.... the .025 od better you have left will general get you at least 5-6 freshings if the rest of the stuff lives that long.

Being that the .160" is at the minor trust side I'd think I't be okay. I thought the Eliminator block were susposted to be .200" 4.700"?

Been running my block since '93 , only has 1100-1200 passes on it at 1200-1650 HP !

Re: sleeving Eliminator Premiere block
forgot to add , the motor has an honest 950- 1000 passes on it since I put the sleeves in at a bore of 4.6000" , there now at 4.6035" , now put that in your pipe and smoke it!

Over thinking is pretty much my SOP. Most of the other cylinders had wall damage from little bits of valve material in the chambers and valve spring material on the skirts so an overbore for all the holes was going to happen regardless. So, we are taking it to 4.600 to take advantage of piston and ring package costs never mind a bit more unshrouding of the intake valve.
We'll just have to see if it lives on the next build. It'll be in a much lighter chassis this time and likely fewer street miles.

Re: sleeving Eliminator Premiere block
Bill - why are they so thin in this Premier block? Aren't they supposed to go to 4.7 or so or is that this is, as you state, a very 'early' block?
