318 2bbl to 4bbl: Is it worth it this time?

Yeah, that too. Also "concave radius" the spark plug electrodes and drill a small hole in the ground prongs.

I have never heard of that one....

Just slap that sucker on there, and have some fun. Your mods will never end after adding a 4 barrel, but it is a great start.

Amen! LOL, just have fun.
