Guys I am trying to "HIDE" as much displacement as possible in a SBC motor. I know you can put a 3.75" and a 3.875" crank in a stock 350 block. I know aftermarket blocks can easily swallow a big crank, but they are also easily recognizable too. So, can you stuff a 4" crank in a stock block?
The cam is not a concern, I have a solution for that if I go this route. What I want to know is what size rods to use between 5" & 6"? And is a low compression dished piston out of the question because of pin / ring clearance? And are the oil pan rails too thin to clearance for the stroke? What is the affect on cylinder walls of all this extra stroke?

Thanks for the engine building lesson,
