[oletrucks] casting number help

["Jack Halton" <safesix@earthlink.net>]

The 261 Chev engine I bought has a casting number 3855590 (near as I can
make out) on the intake manifold. I suspect there may have been some
manifold swapping. It could have come from a 216, 235, or it may even be the
correct 261 part.  Can anybody help? Does this number match any of your
engines? It's on top of the manifold, forward of the carb. Thanks in
advance!
