Hey guys. Starting slowly work on my 409 build. I'm having 333 heads done. With some mild porting. And I have been looking at different cams. I found one I'm liking and wondering your thoughts. It's the comp cams pn. 48-601-5 or the 287th7. It has .525 intake and .509 lift on the exhaust. Duration at .050 is 234 and 249 with a 107 lobe seperation. I have build small blocks before but this 409 stuff is a little new to me. BUT an engine is an engine. Oh and my car is 62 bel air sedan with a Muncie m20 and 3.70 rear end. Thanx for any thoughts!
