Big Block 509 cam upgrade choices??
« on: June 15, 2007 - 08:38:03 AM »
Has anyone upgraded from their 509 cam to a newer more modern grind? What did you go with and were you happy with the change?

My engine is a MP 500 Stroker crate motor with a six pack. After 25K miles I'm ready for a change. The 509 has been great but I'm thinking I could get more vacuum, more power and a better idle (especially with the AC on) with a cam swap. I prefer to stay with an hydraulic cam. Car is 95% street driven. Those 25K miles were put on in 4 years.

I would use a Engle, possibly the  K 60  , depending where you want the powerband  also Lunati VooDoo grind have simialr profiles  , both are better for both Vacuum & power

I personally think the mopar .528 cam is the best street cam mopar makes...with 1.6 rockers you get a .561 lift... :cooldancing:

The .528 is an awesome cam but not hydraulic
 the long duration & overlap gives the .509 its sound , getting more vacuum & better idle needs less overlap / duration so no as you take away the long duration & improve the idle the sound is less choppy

Thanks for the replies so far.  I'd rather stay hydraulic

I ran a 590 Mopar Performance cam in a 500 CID. It was awesome.  Although it is a solid cam.  In my experience with a 500 it doesn't need as much cam as a 440 due to it's larger cubic inches.  A more mild cam like the one Chryco mentioned may be great for the street.  It depends how wild you want to go.

On my 496 Cuda, I have a solid roller (254,258 at 50, and .600/.625 lift). An easy adjustment once a year, and this year the valves didn't even need adjusting.  Idles great and makes serious power. After a lot of research, a solid roller is the way to go for big power. The cam is a Crower. I called them up and gave them my engine specs, and how much power I was after, and they recommended this cam.
