DZ Spark Plugs?

[JoeG]

Sam --Rob did performance comparison tests on the dyno and he said he saw the difference with the NGK's performance.I've got an electronic ignition so I can open the gap or file back the ground rod a bit and my unit will fire pretty hot.----- I've got no complains with AC, BUT dynos don't lie, Rob said it performed super. I did however find that the AC 44 or 45 did keep a "STREET TUNE" longer than the NGK IN MY CASE-- also AC 43 is a little too cold if your not gonna blow out the carbon now and again....----------I would guess Rob would be able to give you a number for your Z............

Thanks Joe. I am thinking about using some of my NOS AC 44's for the street. (AC's look better) I have been using Autolites with good results. Maybe the NGK's are even better??!! Need to get the right heat range for the NGK. Thanks!

I'm personally not up on the small block NGK plugs, but our dyno guy should be...

Yeah they do look better--guess it's a sentimental thing........
