Check to see if the distributor cap on the HEI is sitting flat on the distributor.See if it shifted a little on the distributor body.That will make a noise as the rotor spins and hits inside the cap and it will run like caca too.
Will it stay running if you give it a little gas and hold the throttle open for a little more RPM's ? say around 1200 RPM ? Is there any change in the noise as you increase the RPM to around 1200 ?

Is the HEI a real one or an ebay knockoff? Knockoffs have been known to cause grief. You have to make sure that the ignition is solid before moving on to fuel. No spark no run.

Re: 69 427

Salvage yard? GM?

My question was to determine if the HEI is an off shore one that have a history of problems.
