Re: vacuum advance question
Rich, or to all
I just installed the Crane Dist vac advance kit, Installed the limiter, and here are my results, do they look to be in line for the best performance?
I had a Accel, but it did not come with the limiter. Running a New HEI performance dist on my 4.2 with the Howell TBI.
Mech Advance = 12 deg @ 1400
Int timing set at 10 deg
@ 1200 i'm at 20 deg of which 12 is mech/ 8 vac
@ 1500 i'm at 25 deg of which 12 is mech / 13 vac
@ 2000 i'm at 30 deg 12 mech/18 vac
@ 2500 i'm at 35 deg 12 mech/23 vac
Should i be looking to get a slower curve in, meaning i guess to much timing to quick?
