M110 performance project

[Jezzma]

Hello to you all!

I'm about to start this project with my coupe, 1980 original carburated euro M110 with 722.111 transmission, it has just 150 000 kilometers on it.

My plan:
1) Triple Weber DCOEs, 40s.
2) new main and rod bearings
3) cylinder work with OEM repair size-pistons or custom Ross Racing ones
4) Dbilas or AMG -cams (yes, there is a shop in Finland that modifies stock cams to AMG-specs)
5) custom exhaust manifold and pipe, later on
6) adjustable cam sprockets interest me very much, I need your help with those
7) Main, rod and head studs with ARP-stuff
8) Basic head work, seating valves etc

I'm pretty confident about the engine, what worries me is the automatic gearbox. Should I go with the original 722.1, maybe little rebuilding (although it works flawlessly) or get a 722.3? Original numbers of the engine are 156 hp with ~230 Nm of torque.

I'm going to be updating this thread as the project starts/moves on, all kinds of help is very welcome. Thank you and cheers!

And yes, it is going to be a street car, so lots of carb tuning ahead (even though I'm used to drive with a modified Solex 4A1 with warped body, it's working very well after sonic wash and a full rebuild)
