hey does anyone know what's the biggest bore kit i can get for a 1985 350x.

 

I do believe its 393cc or a 430cc with a stroker kit from powroll performance. www.powroll.com is the website. I really dont know of anyone else that makes a big bore or stroker kit for the 350x engine. I have a 350x engine in a 300ex frame and have been toying with the idea of going to the 430 kit in the next year or so.
