[QUOTE="GDTrumbo, post: 473317, member: 10665"] Until you get in there and measure the cylinder walls for wear/taper, you won't know. With that block and it's miles, fitting new pistons may require boring. With that in mind, the block may also need "line-boring" so when the crank/bearing kit is installed, everything is good & straight. Spinning a main bearing sucks! As for the 347 mpg, depending on how it's built, could get better mileage than the 302 or the 331. It's all in how hard the engine has to work. GT [/QUOTE]
