Boring the hole isn't the issue. Boring is around 150-200 new pistons 300, pressing new pistons to rods 100, balancing new pistons 300 + unknown expenses. That is upwards of 1000$$$ unfortantly I dont have a 1k. So I'm just trying to use what iv got for now I'm gonna try and clean up the 318 bores and stick to the original plan. I really havent spent much on the little things like I said I bought a bearing tool for the cam bearing for 68 bucks I'm sure I can resale it and 12 bucks on those measuring tools and 26 on a hone. Alot cheaper than 1000$ lol
