3885069 BB Intake Manifold?

[Steve Miller]

Anyone know what the application was for a GM aluminum big block intake manifold with the number 3885069 stamped just to the rear of the carb?

Thanks Clem

Was this from some passenger car, Chevelle, Impala, etc? Or can't we get that finite.

Steve----

The 1967 L-78 (396/375) was used for exclusively for Chevelles and Camaros.

Was also used on '66 L-72, '67 L-88, and (possibly) on '68 L-88.

Thank you all for the responses.

I was told that it came off a 67 L-88 along with the 855 Holley, 3419-1. I think it ended with a -1 anyway. It currently sits in my 66 on a 427 (TO6I5ID) - where can I find the application of that block?

Thanks again.

I ment to type 68 not 67. It would be hard for me to believe that I could have ended up with the intake from one of 100 or so remaining L-88's of the 21 originally produced in 1967.

Steve -

I show the "ID" suffix as a '66-'68 427/425hp from a full-size passenger car.

Re: Follow-Up Re: 3885069 BB Intake Manifold?

The "069" was also used on '66-'68 passenger and Chevelle 396 and 427, '67-'68 Camaro 396, and '68 Nova 396 applications.

Re: 3885069 BB Intake Manifold?

i checked the NHRA listing and it is as follows, 1965 425 hp/396; 1966 375 hp/396,425 hp/427; 1967 375 hp/396, 425 hp/427; 1968 375 hp/396,425 hp/427,430 hp/427. the 1967/68 425 hp/427 are most likely COPO engines.the specs are supplied to NHRA by GM. these manifolds should be quite common. it does not list a 430 hp/427 for 67 because there was not enought L-88 made to quailify for being legal for drag racing. there are some other manifold numbers listed for some of these engines.

Re: 3885069 BB Intake Manifold?

There were also several versions, even though the casting number stayed the same. The 66/425 vette usage is a 3 port plenum, later units had the 2port oval design like the follow on 3163 manifold, and some were cut down dividers for the L88 usage with the enrichment tabs in the Holley 3418...Craig

Re: 3885069 BB Intake Manifold?

-----NHRA is wrong in regard to the 5069 being correct for a 65 396,as the correct manifold for 396s had no choke facility.I just cant remember the correct number for the 396 manifold right now.396 carb had a choke tube down to the exaust manifold..........Bill S

Re: 3885069 BB Intake Manifold?

they list both the 163 and the 069 for the 1965 425 hp/396. these specs were supplied by GM and they probably were covering all the bases as they were sent out early in the year.
