I've run the old 509 and 528 solid. but are fine...I'm guessing the 509 is a more racy cam. The 528 worked very well w/ my 6-pack. It was in a 11:1 440 w/ headers, 3800 stall and 3.91's. I set the lash tighter than recommended. It pulled a ton of vacuum (15) @ 850rpm and was more street friendly that the old 509. Car weighs at least 3800, never ran that combo at the track. Spun a bearing and replaced the short block. [IMG]http://i66.tinypic.com/pui5j.jpg[/IMG] Coming soon!!!!

Run with everything from 2.76 to 4.56 gears. The 509 always needed a loose converter and gear to run well and sooner or later would spear a factory stamped rocker from the required spring pressure. No opinion on the "new" 509 as I have not run one of those. "I think its got a hemi"
