first off how do you check to see if a ign,module is bad,if I set my dist in a certain spot it will run great but if I change it either way it will run like **** and I cant find the sweet spot again,could this be a bad dist,module or ground?I have the block grounded good is there some way that the dist isnt getting a good ground I have cleaned it off and made metal to metal contact at the hold down clamp could it be possible that the intake is not getting a good ground?I have tried two different hei's and same problem please help...

Cam is the right posistion and balancer has not slipped it just seems like something electrical when you just move the dist a little bit it will die or run like **** Anyone one else?

try running a different power wire to the dist. if you put two different ones in.. it sounds like its electrical coming to the dist. run one from the battery direct to the dist to bypass all your systems switches..

I got it to idle but the mark is jumping back and forth,Is there a way to check the ign module with a multi-meter to see if its bad? the engine is a 350 .060 4 valve relief flat tops 274 cam 313 stock iron intake stock rods stock 305 heads stiffer springs and a 4412 2bbl with 72 jets and all the plugs are black is there a reason it is running this rich?using autolight #26 I think what plugs should I use

A jumpy timing mark can be caused by several things:excess end play on the dist.shaft,worn out advance weight springs,loose timing chain,cam walk.

A timing mark that jumps around and is not steady can easily indicate a bad module. Don't use an OEM or Autozone type module. Get a good aftermarket performance module such as the one by Performance Distributors.

at low rpm with soft springs on the weights that will be normal..does it do it when you run the motor up?

Well I found my problem I took the intake off to put in new lifters because I adjusted them 4 times and they would still make noise,And I pulled the forth one out turned it upside down and you could have used it as a shot glass, cam and lifters are junk,so thanks to everyone that responded
