no,cant bore the 318 block that much,would need a sonic check and be real thin if it did get bored to that piston specs.

cut the 360 crank mains down,get the .030 over 349 stroker pistons,bore your 318 block.

they say you can use some early 318 pistons that are way down in the hole on the 360 crank/318 block,just need to clearance the piston pin boss and skirt to clear the crank weights.

that will make the 346 cubic inch stroker on the cheap.

i just opted for the 349 pistons with the roller cam 318 block..

member "performance only" can cut the 360 crank and take care of the raer oil seal cut with a more than fair price.
