Hmmm, same motors (except the HC pistons), except one is dangerously (???) compromised by running more advance than what it ran coming from the factory.
That's a head-scratcher, for sure.
No. More like a head-shaker.

don't shake your head too hard, i have trouble following your instructions that way.......
i am not expert to be sure, but the euro 3.0 & 3.2 had higher domed pistons that created the the higher compression. rothsport makes a repro of both euro pistions for new applications, which are legal in the spec class i compete in.. these are considered a "stock" according to the rules.

are the euro cams or timing different than the US cars, 3.0 & 3.2?
