[DeTomaso] Air cleaner suggestions

We tested the dog bone on Gray Gregory’s 377 stroker built by Quella’s shop
and my 408 stroker on a Houston chassis dyno. We ran the test because list
members were vocal regarding it being restrictive. The difference in output
was negligible slightly higher on Grays and slightly lower on mine but
probably tracking error. We concluded no difference. Gray runs single
elements on both sides and I run a double element with spacer. The height
of which one have adjusted over time.
If you prefer the aesthetics, go forward with no guilt.
