Re: 2013 Cobra Jet 427
I was comparing the 2010 352 @ 285 hp vs. the 2013 363 @ 330 hp for the SS/GT classes.
The 2010 has a bore/stroke of 4.060 x 3.400
The 2013 has a bore/stoke of 4.125 x 3.400.
Everything else looks the same.
Using the .070 allowed overbore rule, a 2013 looks like it could also run as a 2010.
