my stock 12a (except for a rb exhaust) idles from 700- 800.

 

I have it at 20 and 10 right now for the break in and it feels a lot different than when I was running 26 and 16. But that was with a stock port and this motor hasnt seen anything over 4000 rpm yet. I'm hoping it will wake up after four grand. I was told this is normal for a ported motor. Can anyone chime in on this?

Thanks, Ed

 

it will definitely wake up after 4K i am running the same setup as you and am idling around 1050-1100. and mine pulls great from 4500-7500.

 

1,000 rpm for street use 2,000 for the track
