Casting Numbers

[matt5858]

I have two manual transmissions and a castiron intake that I can not find any place that will give me the casting number and description.

 

Trans #1 has casting #3925847 on the side and casting #3873886 on the tail

 

Trans #2 has casting #3952662 on the side and casting #3911942 on the tail

 

Intake #14096242

 

What are they? HHHHHHHHEEEEEEELLLLLLLPPPPPPPP!!!!!!!!!!

 

Thanks,

Matthew,

 

Check out this thread where they talk about the 3925847 transmission.

I found this

 

"This Bow Tie part is the best stock cast iron (casting #14096242) 4 barrel manifold available.

 

In stock form it will produce more power between 4500 and 7000 rpm than any other stock Chevy manifold. Commonly referred to as a “Marine” intake, this manifold is a cast-iron copy of a Z-28 high rise aluminum intake. The marine intake is equipped with both carburetor bolt patterns, is 1.250" taller than regular intakes and was not available – in cast iron form – on any production cars"

 

 

I think the numbers from the trans are only case numbers. Are they aluminum or iron and how many grooves on the input shaft?

If you know someone in parts dept.at your local chev. dealership they can check #'s and ratio & what it came in. They will need case,tailshaft,& side cover #'s. I just had this done last week. Hope this helps you out.
