A larger gap means a bigger spark, which in theory should promote better, more complete combustion. But a larger gap also requires more voltage for a good spark, which is why 9V points systems generally use .035" and HEI gaps are larger.

Can anyone tell what the gap size does. Why are some plugs set at .35 and some .45, etc. Thanks Craig -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of James Strunk Sent: Wednesday, February 25, 2004 8:16 PM To: The Chevelle Mailing List Subject: Re: [Chevelle-list] Spark plugs Hey,I gap my plugs @ .060 w/ my HEI in my 70 big block ----- Original Message ----- From: [EMAIL PROTECTED] To: The <mailto:[EMAIL PROTECTED]> Chevelle Mailing List Sent: Wednesday, February 25, 2004 7:37 AM Subject: Re: [Chevelle-list] Spark plugs You'll be fine with the same plug but you can open up the gap to .045" or .050" to effect a larger spark. Brad O. _____ Hi Everyone......I recently switched from a points distributor to an Hei system on my 327.Should a person switch to a hotter spark plug as well.I am running the stock ac delco R44s in there right now.Will the Hei system burn out those stock plugs..???...Was just wondering ........Thanx....John
