Spotbiltxo 'Bolter S Joined: Jun 2008 Posts: 1,644 San Antonio, Texas, USA	Need some help identifying a NOS GM rams horn exhaust manifold I bought at the Decatur swap meet last weekend. It's got the original paper band still on it which reads....... GM Parts Div. 372243 GR-03.601 01D7 __________________________ The actual casting numbers on the manifold itself are: 1408 1238 (stamped just like this, one # over the other) on the backside is the number... 13L6F If anyone can decipher these numbers so I can know when it was made and what motor and vehicle it was originally made to fit on I would really appreciate it. Many thanks, Chuck Chuck 1950 Chevy 1/2 ton (all original) 1951 Chevy 1/2 ton (future streetrod) 1941 Chevy coupe 1938 Chevy coupe streetrod

Would still like to hear from anyone else that could lend some specific help or point me in a direction to find it myself. Thanks for your help Flxible.
