what do you think will happen
 

Ok I want to get the MSD ignition but do not want to regap to 10 like it says you have to do. The only reason I don't want too regap is becuase I can't cuase I got the Bosch 4s. So what will happen if I put on the MSD with the Bosh 4s I got on that are gapeed @ .05 instead of .10. If is possible I would like to do it if not I am going to wait till Ineed to change plugs. I know too that Bosch 4 are not that good for chevy but that is not the issue ok.

Only one way to find out for sure!!!

Although I would suspect that MSD would know what works best whith there system.:D

I thought I remembered reading somewhere that they could be gapped anywhere from .05 to .10 with an msd igniton. maybe not though.
