The reason is that I have a spare cg10 and cr12 engine to youse with on cost involved bar gasket and time,did consider fitting cg10 head to cr12 but not sure of oil feed would work.
Thanks ,looking for flexibility rather than power , The munga is permanently in 4 wheel drive so power hungry ,the cg10 currently fitted works well.Would just like a bit more power when off road .I have some video posted on the munga forum of the cg10 road test.
Looking to make a more flexible engine for youse in my auto union munga ,currently running a cg10 with Lucas distributor and 1 3/4 su on a modified 1.6 rover montigo manifold.The flywheel has been reduced in size by around 50 mm with a kubota ring gear Suzuki alto starter fitted .
