I'm struggling to understand why anyone would make an already undersquare engine even more so. Maybe more off-boost torque? Crank harmonics would also get worse with smaller journals and less overlap. Hardly worth the trouble if you ask me.

Faster spooling and because you can. I wouldn't do it, but it is nice that people do try these things. Your points about the effect it will have on the crank are correct and are a turn off for sure.

Yep. Just need to improve the efficiency of the head and wind up the boost. But hey, each to their own!!!!

& then at the smaller Ci end of the scale there was the Joe Gauci/Profab's TC/TD Cortina with a turboed 200 xflow

running 8.58/158.56mph, I have a old magazine artice of it somewhere.

I wish there were more 221 cranks around. That would make for a nice square engine. Ford Argentina made them for much longer and were the basis for lots of 6 full race engines.

Here, they were rare to start with (only XW had them) and a lot would have gone to scrap. The rest went into red motor 236 strokers with the Holden flywheel flange welded to the cut-off Ford rear journal. But Fords are shit remember?
