I have some problems with those Holley dogbone cleaners: first they now cost 
$250. Second, they weight 12 lbs while a less showy 14" dia paper filter 
weighs 2 lbs, costs 1/5 of the dogbones and has more filtering capacity. Those 
filters can be doubled up on each side by adding longer mounting studs, as Forest 
Goodheart used on his Magnecharged 392 stroker- he has major clearance issues 
which is why he ran it.. He seemed not to have much air restriction with the 
quad-filter mod. 

Sometimes its not the air cleaner itself but the fact that air into the 
engine must make a VERY sharp turn from the side-mount filters down into the carb, 
and the clearance between top of carb and inside of air cleaner casting is 
quite close- hence restrictive on some setups. I've fixed a few of these things 
by simply adding a pop-rivited 1-1/2" sheet metal spacer around the air cleaner 
mount such that it stood up an inch higher above the carb. The engines 
appeared happier and revved higher after adding the spacer; whether any more power 
appeared is unknown. FWIW- J DeRyke
