So good afternoon, I hope that I am not to wordy my questioning, but just because our big blocks come with the the sunken stock 60# intake is it the correct choice for our coaches based on flow and reliability? There are plenty of aftermarket options that will of course trigger modifications but flow and technology on today's aftermarket options are they truly better?

At one time the Gary Rockwell aluminum option on bdub's site was in reach but not now as there is no link to purchase. It's difficult to throw $$$$$$ at an intake unless someone has a rational opinion on benefits to justify spending the cheddar. Running cooler in my mind is not a huge benefit unless other options come into play.

Increased flows or more efficient airflow
More torque
Fuel efficiency
Increased longevity
Performance
Maintenance
Exhaust crossover elimination

Is the stock iron manifold truly the right choice for fuel injection and our coaches based on current aftermarket intake technology/ choices?

If one really wanted to make interior changes on the coach Edelbrock, holley , offenhauser have "torquier" options for new intakes. So any of our .GM engineers have an opinion and then is there any justification to swap out our boat anchor for the $1,000.00 aluminum option? I have read multiple issues in the threads of the port lining up, must use a special gasket thickness for optimal alignment etc. to justify $1,000.00 investment?

As I have notice the trend from our GM engineers on the treads is don't mess with the original. So I suppose the stock cast iron intake is perfect?


Thanks for everyone's support.
