intake manifold id

[Hipshot]

hi! & a happy happy.. i pulled the engine from my truck & i am
trying to id the intake manifold..it is aluminum factory with the
markings gmc fm 14057053 with a large 22 below it is a egr..
the engine was a 305 1980 to 85. i have been told it may be
off of a vette or camero. i am wondering if it would be good
for a mild built 350? it is a 4bl spread bore..thanks in advance
for any help.
