Hi, I'm new to this site and need assistance in choosing the right 454 for my application. I have a couple of deals on some stock 454's and was looking for 1 with a 10;1 or higher comp. ratio. Would there be a particular year range or cast number to look for? Would I have a better chance getting a stock 427 with that ratio? Would the right heads raise comp. ratio? All insight is greatly appreciated,

THANKs
