What is the 1911cc configuration often referenced on this site?
2.0 head chambers or 1.7/1.8 head chambers? Stock cam, RAT 9590, WEB cam 73? (Assuming using stock yellow injectors, D-jet) Has anyone ever built a 1.7 with relocated spark plug (to 2.0 location) or with WEB cam 73, RAT 9590 or is that displacement not large enough to gain from those improvements? |

Basic 1911 is 96mm P&C (slip right in, with no machining) and stock 1.7 crank (66 mm). Changes the stroke ratio so it revs up quickly. If you swap to the 2.0 crank (71 mm) you get 2056.
