Why the overbore from 396 to 402

[55chevy]

I can't remember ever seeing a 400sb in a Chevelle. Seen plenty of them in Monte's and Full Size but that's not to say a Chevelle never had one. [img]/ubbthreads/images/graemlins/dunno.gif[/img] The 400SB was a fairly mild engine wasn't it?

400 Turbo Fire was SB 400 Turbo Jet was BB
I think the "Malibu 400" was a model name

I don't know about that Joe. The one I saw, I'm thinking it was a 71 but it may have been a 70. It was a real light green color, like the sea-mist green that almost looks silverish. It had the malibu interior, malibu dash, I think it had a black vinyl top, but it was factory ordered with a 402bb. Standard orange valve covers.. pretty sure it was an automatic car. 400 decal on air cleaner and the body emblems had Malibu on the fender sides behind the front tire and the slanted 400 emblem on the fenders in front of the wheel opening. There was no doubt about the car, it had a build sheet and everything. Now that I think about it I'm thinking it was a 70.
