I have a small block in a '62 Nova. Not the original. Numbers are VT 207MS, 3814678, and 18W258495. Anyone know what this motor is? Thanks

3814678 is a part number for a 4barrel aluminum intake manifold for a 63-64 Chevy 409

Google is your friend;)

Hi, Try mortec.com or yearone.com tech pages.If you can't find it there send me the casting numbers from the positions shown at these web sites and I will try a couple membership required sites and/or my reference library.
