o.k. If I usev6rods I can use 350 pistons? I am sorry if I ve got every one confused,but there is an article by doug anderson I found on an s10 site on rebuilding the 262.He says there are several types of pistons and rods,heavy and light.plus towonda and romeul us engines.MY confusion came when I read the hot rod mag. article on building a 300 hp. engine.The engine I want when I am done would be around 250 or so hp.The reason I am looking at everything now is I am the cheapest guy in town,so if I know what to buy early I can look for cheap.If I am not explaining things so you guys please post so I can make myself understood. thanks for your patiance with an old fart p the g
