If your new Blaster 2 has runs at a higher voltage than what you were running before, you should be able to take advantage of by using a larger plug gap. If this is the case you may see increased erosion on the plugs & may want to consider a different electrode material. If it runs at the same voltage you will probably need to use a similar gap as before.

I swapped in a GM HEI distributor into my Jeep. From 30,000 to 40,000 volts. Stock .035", now .042". I can notice a difference. But there are other differances between the two distributors also.
