Right now I have a decently built 427 BBC. I am thinking about selling it though for a few reasons. My heads, block, and crank are all Matching numbers 427 435 hp for a 69 vette and I think I could sell those and get something bigger and better. Plus I am running hypereutectic pistons, and gm dimple rods at 10:1 comp with a 750 cfm carb. It sounds great and runs well but I was thinking I could probably piece it out and sell it and build something a better with better flowing heads, bigger carb, forged 4340 internals, H beam rods etc. I was thinking about doing a full mechanical roller N/A 496. But if I were to keep the 427 I am kind of thinking of adding nitrous or a procharger into the mix as well. I know for sure I would end up going with different heads, pistons, cam, carb, and fuel system. Ultimately I would prefer to build a new engine from scratch but I have no idea what the chances of me finding a buyer for my stuff would be right now.
