557 A-heads

Looking for some ideas on crank, rods, pistons, and compression. I will be using a Stock 460 2 bolt block for the build. The combo will be going in a 2800# notch back mustang that 75% track, 25% street. I want to run e-85 and didn't know where I need to be compression. I read and have been told that it could be ran safely as high as 15-1. Shoot me some ideas on the short block. I haven't purchased anything yet so, its all from scratch. I will be building another short block with a eliminator bock later down the road. Its just not in the cards right now.
