What are you guys running for air cleaners? I wanted to make my '72 K-20 look like it had a 4brl intake, carb and headers from the factory, and I planned on running a air cleaner housing off a small block on my carb..........Wouldn't be a problem, except I have clearance issues with my stock power brake booster........So that housing is pretty much out.......And going by our one '69 C-10 with a 250 without power brakes, and the stock intake, carb, and exhaust, it doesn't look like the stocker would even clear the booster.......What are you guys running? I may cut and weld some aluminum tubing and run the one off the small block, but I am leary of the angles that would need to happen to move it away from the booster.
