You makes doubt.....and thanks.

without any accuracy i take a look...

its really close to 131 instead of 140 :oops:


24v 3L

1 : 61.5+4.75=66.25mm
2 : 32.7+4.75=37.45mm, 32.7 to flat top of piston, and 4.75 is the heigth of the crown.
3 : 130.9mm
4 : -ID small end 20.005mm +/-0.005 (inside the bushing)
-ID big end 55.5175mm +/- 0.0065 (inside the rod)
5 : few sources for this…blue print from factory sounds impossible to get, but the workshop manuals are easy to get from a friend or from alfa versus money or the easier way in peer to peer software like emule or others; just type ‘alfa’ and look for everything beetwen 50mo and more like pdf’s and workshop manual names ectect…

i modify it on the top.

see you soon.

Thank you junglejustice for the insite.
yes I've considered bore & stroke issues.
Since my project is only for street application,
going bigger bore for more capacity makes
more sense especially when you factor in
the fact that the stock innards have to be
replaced with stronger parts in my case anyway
as the engine is going to be turbocharged.

Thank you again.
