Depends on the combo....and what the cam is set at WITH a degree wheel. Over the years I've found that 383's like the 509 better than the 440 did but they have to be set up with some advance in the 383....like 4 degrees advanced....at least.
What was the cam set at?
I have some experience with the old .590 and found they also like some advance dialed in even with a 440.
Are you building the engine or is a shop doing it? If it's a shop, I hope they have some experience in Mopars. Keep in mind that aftermarket pistons are never what they are advertised as.....if they are advertised at say 9.5 they will do well to make 8.5. The advertised compression is always (what I have found anyways) the max that you can achieve with thin head gaskets and the smallest combustion chambers available.
Also, never just install a cam using the 'dot' method. ALWAYS degree it in! The dot method is a crap shoot. Yeah, you'll hear about the ones that do it that way and never had a problem but you hardly ever hear about the ones that had problems or even wrecked the engine on start up because the 'dots' were not in the right place or the cam wasn't made on spec? And it happens. Who will admit to doing that!!?? lol There's LOTS of info on the net about cams and you would be wise to learn about them.....yeah, it's 'cornfusing' at first but even if you learn the basics, you'll be ahead of many. Not saying anyone here has done that but.....the more you know, the better off you'll be. Sorry for the long post.
