here ya go

 

i almost tried it on my brother's 94 burb (350) just for kicks & giggles to see if it worked, but he decided to trade it on a camaro

 

Lower your burb and you'll see better mpg.

 

Not sure what is going on. You put the bowl under the air cleaner? That raises it up some?

If you look through the top of your stock air cleaner assembly, you can see that there is so much stuff in the way that little air can get by it all. The bowl gives the much needed extra room and allows a easier path for air flow into the engine.

To be something so simple, I have heard excellent feedback from this.

 

Looks like it is time to dig through the bowl cabinet!

 

Somewhere around here, there is a dog food bowl that would be perfect for that. I have been patiently awaiting the day I stumbled on it.

 

Well I filled up today and at 410 miles it took 41 gallons. That is 10 mpg on the nose. I might have done a tiny bit more hi way but it should be about the same ratio of city and hi way. I am probably going to get another tank at least as is to average them out and see if I can duplicate the 10.0.

 

flip the aircleaner lid and buy a throttlebody spacer if it's a TBI, don't waste your money on a TBI intake manifold.

Drive it like your right ankle is broken
