Hey folks, I am in the process of building another motor for my 87 GN, and I am wondering about the billet main caps that will supposedly strengthen the bottom end of these motors. My question concerns the reliability threshold of the stock caps. Are the billet pieces needed for an 11.50 car for instance? I am building a conservative motor, and will be happy with mid elevens or so. I already have the caps, so I will probably use them, but I am having a hard time finding a machine shop to do the work locally. I just wanted input from those of you that have made this choice before. What were the pros and cons of the stock caps vs the billets? Thanks, Rudy E.
