LOCKED OUT TIMING
(1)WILL I GAIN ANYTHING BUY LOCKING OUT MY DIST.
(2)IS IT WORTH IT? (3)WHAT ELSE NEEDS TO BE DONE WHEN DOING THIS? |
In my case I started without locking mine. 383, 11.3 compression on alcohol. When I did lock it out I found that it started easier and would build RPM faster, I.E. better throttle response. This is on a drag only motor. I didn't gain anything in e.t. because leaving either off of the foot brake or trans brake, in my case, I was already above the RPM to bring the advance all the way in. Coming up against the brake was better/quicker though.
Curtis P.S. I changed nothing else but locking the distributor so I would know how it acted differently. |
jeff if your talking about a bone stock motor then easy answer no.if it has mild cam and gently warmed over then prob not. if its a nasty cam with big heads and gonna see lots of rpm then yes. on my bbc with big roller cam its a turd with anything other than a locked out distributor. depends on your application and mostly cam selection

In your case absolutely. We found even with duration as small a [email protected] on a tight LSA, 106 to 108, they responded to locked out timing. Unless you are running less total timing currently, start at about 36˚ and work up 1 at a time watching the plugs ground strap. The heat line should be mid way in the bend of the ground strap. Start with fresh plugs. Also stop and go back 1 if the ET or MPH falls off.
