Baz you stole the words right out of my mouth. To my thoughts, you hit the nail on the head - but as you said, we can only speculate.

Cool name Jack haha

Both can be built.
6 bolts were the earlier and probably over engineered. In my opinion, 7 bolts were brought back in line (over engineering brought back in line with target requirement of Mitsubishi).

What this means is they probably recognised that:
- Rods were big and heavy. Could be improved by lightening.
- ports were too big and reduced to over velocity
- head studs were too big
- eng mount to transmission mount design change may be related to either efficiencies to labor or structural improvements (bell housing support).

Wouldn't be great if we actually had a chance to get the thinking and calculations behind why Mitsubishi engineers did what they did (performance or manufacturing influence).

End of the day, most have the option of building whatever 4g they have. Most influential preference is based on the chassis they own. I know many wouldn't go out of their way to convert.

With that in mind, I like 6 bolts because I own Galants.

 

That's the best post I've read in quite a while, very well said Baz

Im sleeping from boredom. There is no good reason to have a 7bolt unless you are stuck with it.

Im sleeping from boredom. There is no good reason to have a 6bolt unless you are stuck with it.   FIXED

admit it you went to sleep to dream about owning a SEVEN BOLT!  we know Jacky boy you love them...this is why you want to make a crappy old 6 dildo into a mivec.

Crankwalk is a great feature of the 7 bolts, haven't heard of many instances in Aus strangely enough?

Nothing like fear of epic failure to keep you on your feet hey!
I think the lack of that issue could be because our cars dont require depression of the clutch to start, unlike, say, the american market cars. This way at least we are able to build some sort of oil pressure before putting some stress on the crank with the clutch.
IMO, 7bolt for simple mods but i would take a 6bolt if chasing big numbers.
