350 intake manifold verification

Is there a factory number located on the 350 intake manifold that verifies if it's a Buick or a Chevy 350?

 

Some On the back it’s cast in big letters 350 and there will not be a hole in back for a distributor.

 

also :
chevy t/stat faces up , buick t/stat faces forward .
if laid next to each other the chevy is a way narrower intake .

 

Here's my 71 350 coming out of the hot tank.

350 cast on the back side, firing order on the front.

Hope that helps

 

Wow, thanks for the great info guys, helped a lot. I had no idea that there was an orientation difference in the t/stat.

 

That’s exactly what I was looking for. Thanks, Larry!


Nawaf

 

Thanks a lot for the comparison, Larry. I can see the Buick is definitely way wider.

 

Got it! Thanks for clearing it up, Larry.

 

The 350 Buick intake is wider 'cause its a beefier engine than the wimpy, skinny, narrower 350 Chevy

 

Exactly what I thought

 

LMAO, you nailed it Larry
