Quick question. How big is the opening for the stock intake manifold? 2.5"?

 

I'm not sure of the intake ID, the throttle body OD is 2 3/4". So the intake is close to 2.5"ID.

 

Yep.. It looks real close to 2.5"... The intake manifold itself needs a bit of cleaning up in the runners and plenum, and the throttlebody could use a bit of cleanup and blending, but it looks like it can handle more than enough airflow for anything most of us would want to throw at it.

 

Thanks for the info guys. Always helpful
