what kind of big bore



What do you mean by that? A big bore is just that, a cylinder bored out larger than stock.

Eric Gorr is an engine builder. Send him your stock barrel and he will have it bored and plated and return the parts to you along w/ a Wiseco piston. There are a few compression ratios to chose from. A stock 426 bore is 95mm, Wiseco makes a 97mm piston that will result in 444 ccs.

Your other option is to have the crank offset ground to increase the stroke, increasing the displacement that way (you could still increase the bore also). This is a more involved modification and therefore isn't quite as popular. The only shop I've heard of that does this is Stroker, I don't have a number for them.

Hope this helps.
