Smile Get The Gap Right


I have a Chevy SB 350 engine with a HEI ignition and was wondering what the spark plugs should be gapped at?

It looks like the first year that engine ran without the point/condenser setup would have been about 1974 which would have been the HEI setup. For that one the plug gap was .60.

I think I would just call a parts store with the make and model of vehicle you have and the plug type. That way you'd be sure to get everything right.
