[DeTomaso] Air cleaner

[Dan Mixon]

I just weighted my B&M dogbone and complete with filters it weighs 7 lbs. My
14" dia Pantera script (heavy cast aluminum top) weighs 5 lbs with a base
and filter.

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
