OK good on the timing light and the non-MSD system.

So to be sure, the timing tape's numbers go 0 on the left end and 60 on the right end on the top? I know it is dumb to ask, but am just making sure the tape is not on backwards....It is hard to catch little things over the internet.

OK, your 98 RON is similar to our 93 octane here. The formulation may still change to make the fuel more volatile in winter... easier to fire off when cold. (Diesel mix changes are a different thing.)

Hey buddy.. its actual engraved into the billet pulley so deffo correct way. (wish I knew how to post a pic here as didnt work out above lol!! see if this works)

I'm also informed by Shell that there is no change to winter gas formula.

On a side note guy who posted after you has a valid point... wish MSD had advised this upon purchase as I'd bought the ballast that goes wit hthe Blaster 3, personally I thought it was just the raised lead connection that was different to the Blaster 2 Grrr!! the shipping will cost twice the price of the part, so may just go down the GM HEI module mod and be done with them Ballasts ;-)
