The things that we talked about. Really don't matter as mush as I thought. And for my racing, which is braket racing their really isn't and rules. When I made the statement to Brett that I didn't like a short rod engine. He said don't worry about it they just connect the pistons to the rods. He said you'll never know the difference. So we used the 6.125 rods I had and the engine revs fine. I wanted longer rods. But he said to save that money and buy a really nice set of pistons. And he was right.
