[s-cars] New 5 cylinder vs. AAN

[Stoddard Robin]

Hi Jared,

Sorry, I'm not as edumacated as yourself in the engineering department.  ;-)
Can you explain the advantages of having a .94 under-square block over a .89 measurement?

And thanks for the CEPA designation; I was looking for that and haven't seen it in any docs yet.

Cheers
Robin
