Need help finding correct exhaust manifolds *NON LT1*
This is for a 93 GMC Sierra reg. cab 4.3 liter V6. Long story short: Girlfriend's truck, previous owner claimed the now removed engine to be from a 95 GM fullsize pickup. Engine blows, replaced w/ a rebuilt engine from reputable local engine company (City Motor Supply). Exhaust manifolds now don't fit as the bolt holes in the head are spaced just too much for the manifolds. I've been told by several people that different year model 4.3s had different bolt patterns.
Anywho, this was copied from www.GM-trucks.com:
I'm in a dilema....
The truck is a 93. The previous engine as claimed by a previous owner was from a 95. The valve covers are composite and say Vortec on them if that matters.
I picked up a new engine and now the manifolds that came w/ the truck don't fit. After two bolt holes on the manifold are lined up, the rest come a couple of milimeters short.
The manifold part #'s that I have are as follow-
LH 14101013
RH 14101014
The part #'s GMpartsdirect.com (a subsidary to the sight, not always reliable) lists for this application are:
LH 10045321
RH 14102164
Can anyone confirm the correct part #'s for this application? My local dealer suddenly decided that he wont give out part #'s.
I got no response there (after a week) so I'm turning here
I need manifolds that fit this engine. I honestly don't have the time or $$ to scour over junk yards without proper casting #'s in hand. This is all that's holding me up so I'm about to just buy headers for it or something.
In short, I need to know what the correct manifold part #s are or need to know where I can get that info. As posted above, local dealers have been ZERO help.
I'll post back in a little bit with the head and block casting #s as I don't have them on hand.
Thanks,
Jason

my post somehow got deleted!!!
Anyway,
the first # doesnt come as anything,
the second says discontinued,
the last are for 95+ vortec v6 exhaust manifolds. If that is what you want, then you are ok.
Any 95+ vortec v6 manifolds will work for ya.
this is a condensed version of what I had typed.
