Q: Amazon sales this as a 383 crank not 400 the one i got was a 400 crank 2 piece main wrong crank and is not as pictured .

the eagle part # comes up as a 400 crank..

Q: What year will it fit?

The small block 400 was made from about 1970- to about 1980. these were all 2 pc rear seal, this will fit all of them. there is also many aftermarket blocks this should also fit almost all of them if they are 2 pc. rear seal. I have bean told that it will work with 5.565 inch connecting rods, i have not had a chance to fit this up and check that, as it says it is made to clear 5.7 rods..
