Thanks to all who posted messages to me regarding the manifold. A couple of
resources surfaced that might be of interest to list members. Here is a
link that shows the intake manifold casting numbers. It has other casting
numbers as well: http://www.nastyz28.com/sbcmenu.html This link shows the
manifold in question to be
1966-67 3872783 327 4 iron Holley A B X/275hp, w/o AIR, srvc. repl.
I don't know what srvc repl means (service replacement???). Perhaps it was
a dealer installed option?
Another useful site was http://www.chevymania.com/casting/INTAKE.HTM that
showed the following:
3872783 4-Brl 66-67 220, 275 & 300hp HOLLEY 283/327.
General consensus is this particular manifold was used on 283 and 327
engines and employed a Holley carburetor.
Any idea how to find out WHICH Holley carb would have been used in the
220hp, 275hp, or 300hp engine?
