I’ve never done this scope of a project but I opted for a 4-speed because I thought I could get better fuel economy. Monster builds theirs with generic bell housing thats supposed to bolt on to all sorts of engines to include standard BOP bolt patterns, so Ill not need the bell housing adapter from D&D (saving me extra cutting/fabbing to accomodate the extended length. The adapter would have been required if I had gone with the 700. By ordering their “conversion kit”, Monster upgrades all their 2004R with OD with HD clutches and durable metal vice plastic pieces, they include an Edlebrock linkage set (TV cable) along with and bolt-on Lockout kit and an external intercooler. Did you consider a 200R 4 speed, was it not practical? Is the 200C that much smaller and does the 200C come in a 4-speed?
