Can i use the endyn 81.5 <size, in a stock ls b18b1 block. I will also be using a b16 head. This will be a all motor setup. THe block has around 40k miles. Std size ls pistons. So the block has not been touched since factory. Walls look really good and motor is clean. Can I do it? And what rods should I use. The egale rods are heavy from what i heard, power weight deal. So i think i will be loosing power. Give me some input please. I know honda doesnt reccomend going .30 over and iam using 81.5mm size pistons. Let me know what you all think. I will call endyn later today and find out.
