Casting Numbers

Recommended Posts

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!!!!!!!!!! :D

 

Thanks,

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?
