Hello all, I am changing my plugs and wires and I am not too sure what the proper gap for spark plugs for a small block 350...Parts stores are closed and I have tried refrencing the manual and websites still no luck...also being that I am running MSD should it be any larger or smaller?

FYI

Got my own answer since the parts stores are now open for anyone else's info its .45 gap I am still curious if i should do more or less because of MSD

I think

you do more with MSD. The larger the gap the bigger the spark possibility. With MSD it increases the power so the spark is able to jump a larger gap and therefor give a more powerful and larger spark.

Thats what I understand from a relative that knows his cars he said i could probably goto as large as a .060 instead of a .045 but he said that the difference wont be that great to worry about it
