Slant six in a Miata ? Why ???

My question isn't "why he's doing it". My question is "Does he need anyone's permission to do it ?

Did he say the slant was being installed for performance?? I didn't hear that.

Not at 1st but down the road he wants to do the engine up, wants see what he can get out of a high ish revving 170 /6.
If I was to do a /6 would be 170 got the best bore to stroke ratio.
