340 six pack air cleaner question

Hello, I am ordering some parts for my engine and I just sent out the carbs to be rebuilt. Jegs sells 6 pack air cleaners but does not say if it is SB or BB might be dumb question but are they the same?

Thank You

Yes,,,,,and No,
But will interchange just fine.
technically SB is unique to the application of AAR or TA

ok perfect so it will fit on the 340 carbs.
thank you

No problem.
in a non AAR or TA application Using the big block air cleaner is the way to go .

I am running a 1969 B Body one on my 1973 A Body
But have a T/A AAR one for the Challenger One with wife lip lid {Ben Snobar one}

wife lip?

Hahaha ….maybe wiDe lip?

Wide Lip. hangs down over the filter more.
