[QUOTE="StrayBullitt, post: 15551435, member: 181759"] Hey, yes you can get away with not degreeing as you found out, But the stock gears will put the cams at a 115 intake centerline, ( There can be slight variance, I actually found that my drivers side was at a 116.5 intake centerline) so you are losing out on a few degrees of advance. It's said that advancing will help the lower and mid rpm power while retard can benefit at higher rpm. I can tell you the most significant difference I really noticed after degreeing was the idle quality. I had planned to do a dyno pull after degreeing without any other changes just to see, but I could tell after driving it that it felt about the same and there wasn't a significant increase there, not enough to spend the money. Mine did call for being set at 106, I would set your cams at where they are recommended at 109, that should help, but I bet that you will still need to up your idle speed 50 rpm or so to smooth things out, I have mine set for 755rpm and it ends up running between 760 -800 and it idles great, no complaints and no stalling or anything.
