Why would you go a 207 over a 257 Tino.

Yeah they do oversize pistons, but not oversize bearings (for when you machine the crank).
207 is inherently stronger, can take more boost without splitting a bore, or having bore shift, or anything like that which can affect the 257.
BUT, the 257 is torquey and can still cop a bit of boost (up to around 20 psi) before they start getting less reliable.
OF course, this is from what I've seen and read, not from MY experience, so I'd like to hear an opinion from someone who has actually done 207 vs 257
