Re: Why the overbore from 396 to 402

Engines over 400 cu in were allowed higher emission spec. So they avoided putting some emission equip on some BB engines by making engine slightly bigger. 402 cost them less to produce then 396. They end up making a 400 SB turbo fire and a 400 BB turbo jet that was really a 402 and a 396 that was really a 402. They were crazy not stupid.
