7377 Lancasters were built including the ones built in Canada (430). I don't see where the Lanc had a manufacturing challenge when compared to the B-24.
Perhaps not. Untill we see some manufacturing time data for the Lanc, then the B24 wins
From Wikipedia
The majority of Lancasters during the war years were manufactured by Metropolitan-Vickers, Armstrong Whitworth and Avro. The plane was also produced at the Austin Motor Company works in Longbridge, Birmingham later in World War II. Only 300 of the Lancaster Mk II with Bristol Hercules engines were made. The Lancaster Mk III had newer Merlin engines but was otherwise identical to earlier versions; 3,030 Mk IIIs were built, almost all at A.V. Roe's Newton Heath factory. Of later versions only the Canadian-built Lancaster Mk X was produced in any numbers, built by Victory Aircraft in Malton, Ontario, 430 of this type were built. They differed little from earlier versions, except for using Packard-built Merlin engines and having a differently configured mid-upper turret. 7,377 Lancasters of all marks were built over the war; a 1943 Lancaster cost £45-50,000.
The B-24 was produced in massive numbers due to the people and resources available.

If thats true, why was the B24 built more efficently and faster than the B17?
Because unlike Lockheed, Douglas and Boeing who built their subassemblies in "segments" and moved them to various parts of the plants for assembly, Consolidated teamed with former automobile manufacturers who developed automotive type production lines for the B-24 where the whole line moved, that why Willow Run, Fort Worth and the Old plant in San Diego are so long. Henry Ford's VP of production (his name escapes me) assisted in setting up Willow run and several other Consolidated facilities. Although achieving numbers, Lockheed Boeing and Douglas for the most part did not adopt this on their 4 engine bomber programs and stayed conventional.
Lockheed did adopt this assembly methodology on the P-38 line being produced in Burbank plant B-1. The line had a steam driven chain that actually moved the entire line of aircraft being assembled.
Don't forget the first Lancaster flew January 1941, the B-24 was already in production.

The B24's production didnt ramp up untill 1943. Remember many of the plants that were to build the planes were still being constructed in 1942.
Ramp up? By 1943 there were several hundered B-24s in service, 177 attacked Ploesti in August 1942, the Lancaster first models were't deliveered to squadron until April 1942. What happened in 43 was willow run put the production into "overdrive."
For the Brits to build almost 7,000 Lancaster's is a commendable feat. they did not have the manpower or resources like we had here in the states and also maintained the "segment " production methodology....
