RE: Need opinions on rebuilding 440
The cam I'm running in my 440 is the 484 purple shaft. It is a real good choice for an automatic with a stall of 2000 or less. I have heard that the 509 is a good choice for street duty but if the 528 is streetable then I'd go that route. The fact that he has a 4-speed lets him be a little more liberal with the cam selection. Any help to make the 550 hp goal is good. I don't think he will have a problem making over 550 hp.
