Re: What air cleaner in a 4wd?

The reproduction GM drop base air cleaner (65-71 Corvette, 67-69 Z/28) sells for about $50 base only and drops significantly more than any of the aftermarket dropbases and is profiled to clear a Holley carb

On my Jimmy I have a no-drop base with a 4" K&N and it clears by just a little. The stock setup with the spacer that connects to the valve cover vent was so tall there is usually plenty of room in these trucks.
