|IMPORTANT NOTE: In order to build a .070 oversize 360 you must have an engine block with thick cylinder walls. For stock 360 blocks, the majority of the 1971 blocks can be used. They were cast using the 340 molds so the cylinder walls are considerably thicker than the later model 360 blocks. You can also use any of the aftermarket high performance and racing type blocks. If there is any doubt at all about the ability of your engine block to be safely bored .070 oversize, you should have a high performance machine shop sonic check the block to check the wall thickness for you.|
