Instead of boring the 261 way over, do a search on the Inliners.org site and order the back issue with the Caddilac 261. You can offset grind the stock crank and fit caddy pistons (and rods, I think) and make a 261 stroker with less piston and rod mass and keep the same rev range as the stock 261 with a heck of a lot more torque. Good 261 blocks are going to get more scarce and don't bore them any more than you have to.
