318 poly motor can selection?

[Torkmnstr]

hey all I have a 66 ploy with a .404 cam it already. All the springs are stock spec and all, how big can I safely go? I am not sure what the stall is, but I'm assuming pretty stock...it's got a sb 727. I bought it with the current combo, just looking to wake it up a bit. Thanks all!

Check with "Racer Brown" for his camshaft selections. Purchasing springs to match the cam would be a good idea. Also, without pushing it to far, a cam lift of .500 or less would be smart.
