Automatics with ZL2 ducted hood

[BillG]

I bought an apparent NOS stove pipe for my engine but its about 3/4" too long.  Did automatic cars equipped with ZL2 ducted hoods, get the same stove pipes  as  standard four barrel air cleaners, or was it a different part.  AIM only shows standard.

The ZL2 stovepipe with automatics was different. Look in the AIM, section M35, sheet A22 - shows 3942530 for the base 2-barrel automatic engine, and 3942531 for the 4-barrel automatic engines. ZL2 shows 3951636 for L-48 automatics with ZL2.

Thanks for the information John.  I always feel fortunate to hear from you.  Now I know why it doesn't fit.  I'll bet this is going to be a tough part to find.

Bill, if you still have the heat stove pipe please contact me. Les

I used a 2-barrel one and reshaped the bottom end .

Thanks Mark.  That may be an option.  I'm hoping Bill will reply whether he has the part he couldn't use.  The same part was used from '69 thru
'81 & yet they're tough to track down.
