The 907 suffers from short stroke, low compression and mild cams as well as carburetion. It's easy to bolt on the parts for about 180 HP. Flow work will take you to 220 HP. Up there crank fired ignition is more important. Block flex also becomes an issue.
A late 912HC engine with it's stronger 2.2L block, cams and better flowing heads may be cheaper than building a 907.
How will you get the Mukinis jetted? That's got to be costly. You can get jetted Dellortos with manifold for 220 British pounds from Mike at Lotus Bits.
