440 Blowby near Carb base

[67SniperHockey]

Hey guys - getting the car ready for the year - doing some testing, new alternator, etc.

When motor got to operating temp I noticed some smoke/blow by near the carb base on passenger side - behind and below the electric choke (eddy 1411). Never noticed this blow by before.

Thoughts? Thanks.

If you have a 1970-1972 factory intake or a Mopar M1 dual plane then there is a cup and gasket there that can leak exhaust.


What are the casting numbers from the intake?

2806178 is casting on intake.

Thank you!

I see a cast bowl in the intake below the carb - wonder if some carb cleaner is in there and is just blowing off once it warms up? This seems to be the area in which the smoke is coming from:

Likely just crummy old fuel in there getting burnt off from exhaust heat
