Can anyone tell me what the timing spec for a 1984 351w should be? Got her running at 10 degrees now, but still doesnt seem right?

 

anyone??

 

Whats it doing that doesnt seem right?? I got my 89 302 set at 14 degrees

 

Just seemed to stumble if you crack the throttle hard from an idle. Otherwise it runs pretty damn good. Yesterday i played around with the timing. Moved it to about 12 to 13 seems to be better, but if anyone could tell me what the orginial setting would have been would be a big help. Thanks

 

stock is 10*. maybe your timing chain is no good?

 

NA really dont think thats the case the motor has less then a hour on it. Just rebiult the thing myself. New timing chain and all. Thanks for the info though. Could be that something else is the problem and 10 is where it should be.

 

could be the advance isnt working right. I would check that out make sure it advances the way it should. Get a haynes book. I dont even pay attention to the idle timing in my Cleveland but its a differnet animal. I have it set for 30 degrees maximum advance all in by 3000 rpm..

 

Yea the cleveland is a whole diffrent ball game but you may be on to something. I was wondering about that. You would think that it would be correct being that it is a brand new Procomp electronics system. Ill look into it and let you know what I find. I thought that the repair manual that I have by haynes said that the stock dura spark system or whatever they call it is non adjustable. It covers pick ups and bronco 80 thru 96. Did I overlook it and its been in the book all along???

 

did you replace the torsinal damper aka harmonic balancer. The inertia ring rotates around the hub on the old ones when the rubber dries out.

 

Procomp is garbage. Chines ripoff knockoffs. I would use a junkyard distributor first. Depending on witch one you got some of them are awfully ugly to. GM looking things yuck.
I have an MSD pro billet distributor that is adjustable. Your probably isnt. It should mimic the one they copied..

 

well we know your opinon lol... ive been using them for years never had a problem.. its no msd but for less then half the price it will do just fine im not out to turn any drag records... And yes im 100 percent sure that it is adjustable. oh and its the orginal balancer.
