Re: ever drilled and resleeved a lfter bore on inl
Somebody used to make a roller conversion for SBC engines where the lifters had 'cheeks' that hung down below the bottom of the roller. The shaft was turned small enough, and the sides of the lobes were finished, so that the cheeks straddled the lobe and kept the roller straight. It might have been Iskendarian.
To sleeve the bore directly from .905 to .840 would take a sleeve with .032" wall thickness. As Leve says, with a hot block and refrigerated sleeves, and a good installation arbor, it might be possible to press them right in. You would have to have a good grinding shop make them for you, because they would have to be VERY precise. I would guess that it would would be a $200 to $300 to grind the ID and OD. A lot cheaper if you could get the stock with the ID already sized.
It does seem like one of those ideas that will turn out to be more effort than its worth. What is your goal for this project?
