L-8828 is 4180 that was used in 1980-81 Ford HD trucks w/ 429ci engine and a manual tranny. I don't know the cfm, but I suspect it's 600-650. It has 62 jets in the primaries, and a plate in the secondaries.
L-6945 is a 4150G (600 or 650cfm) that was used in 1975 Ford trucks w/ 361ci. It came with 64 jets in the primaries, and 70's in the secondaries.
Take care,
