Mike, I am running a 410 dana in mine and a 4 speed. I also am installing this in a 400 block 499 11.5 to 1 compression. Im gonna break the engine in by installing it in my m46 barracuda, then pull it and install the 318 next year. I will eventually sell either the 446 6pack engine that is in my car now or the 499 six pack engine. I just started to build a 452 rb this afternoon, but im going to take my time. I am hoping this cam I chose , ends up being a good all around cam for bigger cube engines.
How big is yours Mike? 10's with a hydraulic is a good run to OS
