Does anyone have hard data on this? Specs for certain part numbers listed? I keep seeing this thrown around but no one has the evidence. Only that the part numbers are different.

The coil pack bolts for a L36 are different from an L67. Doesn't make the L67 bolts any "better". Just means they more narrow by a half millimeter. So just because the part numbers are different does not mean the L67 coils put out more spark. Most manufacturers for coils use the same part number for both. Only ACDelco/Delphi use different part numbers and they're known for using a different number for the most minuscule difference in design.
