Default Re: ZL-1 Spark Plug Gap

Also I did change the power valve from a 6.0 to a 3.5 since the vacuum at idle was about 8. That helped alot. Car has headers and flowmasters and runs strong. The idle is smooth (as smooth can be) even when I opened up the gap to .044. That change really made a big performance difference
