Does anyone know if a 290 block has the sam main webbing thickness as a 360? Basically, I want to know if a 290 block is as strong as a 360 block.

1973 Javelin AMX in pieces.
A standard 360 block appears to not have a significant amount of extra material. Of course, the 360 service blocks that were made from 401 castings and the 360 "TransAm" blocks have more meat down there.
