A suggestion on the decals, if you're applying to a flat surface, use some gloss clear to make a nice shiny surface for the decals to adhere to. Then use flat clear over the decals to seal them and secure them. Seems like more work but works really well.

iiiat, I originally tried a 15x8 but dropped down to a 15x6. My experience with Magnums has been that they need a bit of an extended break in period. I have a .91 on another warbird, for the first gallon or so it wouldn't pull larger than a 14x6, but I noticed that it was revving higher and higher so I switched to a 14x8.
