[DeTomaso] 180 degree headers

[Mad Dog Antenucci]

What negatives?
  You don't need luggage space unless you are gay or a girl.....NOTHING sounds like 180's at WOT. Novices who look under the decklid see those monster headers and its the first and last thing they remember.
   
  Bobby Byers has a polished SS heat shield that is installed on the bottom of the deck lid.It's very unobstrusive and provides the necessary air/heat gap between headers and paint.

  The only one of the guys using 180s that dynoed before & after was Jr Wilson 
& his monster motor, and he said 180s slightly increased mid-range but cost 
him 200 revs on the top end. So he took them off after one SS run. If this holds 
true, its probably simple gas friction in the much longer tubes that limit 
top end power; longer primary tubes will usually increase mid-range torque by 
resonance.

I raced a set of Hall 180s for a dozen or so events and the exceptionally 
sweet sound they produce will coax you to stay in the gas a few milliseconds too 
long- I spun more during that year than ever before or since. Working on an 
engine with 180s is not much fun from the top, especially changing plugs, and if 
you install 180s, be sure to add a heat shield & stand-offs under the 
decklid, or they will destroy your paint near the window opening. With no heat 
shield, a 40 mile run to the track BOILED the decklid paint in two 12" dia. spots! 
Good luck- J DeRyke
