Here is the 484... i know it's just a video.. but just to get an idea of idle quality..
And you don't want a .590 He was being sarcastic...thing sounds amazing though
That .484 sounds sweet! What do you have your timing and idle set to?

The engine builder (drag racer) that built mine put in a moderate Purple Shaft Cam (it was in the 80's and I can't remember the #'s now) and new pistons w/ 10:1 compression, block was bored .20 over stock. Idles fine, sounds tough, bad to the bone. He tried to keep it street-able, but just barely.Hello, I have a 383 Mopar that I am completely rebuilding, we are planning to put in a Purple Cam which should be a step higher than the stock one. If we do this would we have to change the pistons or would stock work better? I did some research and I believe the compression ratio for a 383 Mopar is 9.5.1, not 100% sure. I also read that it's recommended to keep stock pistons because otherwise, it'll run crappy unless running a high idle with a purple cam. If someone can let me know whether to keep stock pistons or get a different kind? Thank you
^^^Totally agree. Put that cam in my 383 and required a 3000 stall converter. It really came to life when I changed out the 8 3/4 pumpkin with 3.91 gears.I have a 484 in my 440 with a 5spd TKO and 4.10 Dana.
I would not put the 484 in a street 383 personally without some converter and gear.
When you say more than stock cam do you mean the 2bbl cam or the roadrunner cam?
^^^^ agreed ^^^^^If you got nothing else, but "stock" intake, exhaust, etc. you'll be better off with the 280/474. None... of the others listed.
