Which intake?

[modman]

I'm building a 350 engine to put into my truck and I picked up 2 intakes for the price of one. They are cast iron with the 055 on them. I have cleaned both up and I have noticed they are different. The runners on one is a little larger, not by much only 10 thousandth bigger. Is there a reason for this, or is it just they way they were made.

Not idea.

All I can say is: Edelbrock Performer RPM Manifold.

$100 locally if you check FB MP.

Welcome from Austria. That is production tolerance. Cheap cast mass product.
