[DeTomaso] Gas tank shield question

[Mike Drew]

Owen,

No, not necessarily I don't think?  It depends on the vintage of the car. The earlier cars had a gas tank shield that wrapped around the back side and they don't give much latitude. The later ones used a separate splash shield to protect from rear tire debris and a heat shield for the engine. Although it would be awkward you can do what you want to do with the engine in place. You might have to remove the left header. 

Personally I would probably find a hundred other things that needed doing more!

   Owen,

   No, not necessarily I don't think?  It depends on the vintage of the
   car. The earlier cars had a gas tank shield that wrapped around the
   back side and they don't give much latitude. The later ones used a
   separate splash shield to protect from rear tire debris and a heat
   shield for the engine. Although it would be awkward you can do what you
   want to do with the engine in place. You might have to remove the left
   header.

   Personally I would probably find a hundred other things that needed
   doing more!

     The stock system consists of a riveted-on heat sheetmetal heat
     shield that is faced with asbestos on the gas tank side.  Pantera
     shops sell polished stainless steel covers for this shield which
     slip over the top, and add a measure of reflectivity not to mention
     loads of 'bling'.

     The factory low-performance exhaust manifolds clear the heat shield
     by a fair margin, while the Euro GTS ANSA headers often literally
     touch it, and aftermarket headers are somewhere in between.  The
     tank can be shifted outboard, and the heat shield can follow suit by
     simply drilling out the three rivets which secure it to the chassis
     rail, moving it over and drilling new holes and riveting it again.
