spark plug gap
I'm currently running .035 gap on my plugs. Just curious If I'd be better off running more gap? Mods in sig.

Re: spark plug gap
with the msd i think your supposed to start at .050 and work your way up ? and a side note how is it working for you do you think it was worth the 200 or so $$ ive been up in the air about getting one myself

Re: spark plug gap
makes sense i just read you have something like 11:1 comp ratio so you should have a good starting ppoint, ive adjusted my brothers car based on msd's chart and his car runs 10:1 and his are set at .055 and runs flawlessly it takes trial and error gotta experiment with different gaps
