Big Blocks

Well,the reason I was thinking roller wasnt really because I want a huge cam. Im more concerned about the zinc in oil thing and would be really happy if I didnt need to break in a hydraulic again. Getting a bit tired of that whole scene,lol!!

So the 440 rods are the longer ones right? I can get a set fromthe same guy who has the crank. I think it's a 66 vintage 440? Cant remember exactly.

So porting the stock 400 heads and setting them on my 470 will give me 500+ h.p? Thats what I'll need.I could enquire after the heads on the 440.Would they be better?
