Re: {Chrysler 300} In need of a long ram intake —-How about FIXING it ?

[John Grady <jkg@xxxxxxxxxxxxxxxxx>]

Ps 
I repaired mine with scotch cast electrical epoxy , way back , was highest rated heat , (but $) I had  planned to use it stock again — before I smartened up . Even best epoxy  is in trouble around 275, but ok without heat .  tape on inside of plenum , seal tape with was  cement to be sure no leak  pour in the bottom holes, ram upside  down      . I tried  to get 1/2” thick on exhaust side  to save manifold . It worked , then tied heat open . But always had nagging  doubt about it  w even residual exhaust gas heat — it is HOT 
no heat you are ok  

This past year discovered firebrick cement mortar while fixing sad joke Vermont casting stove ( they crack casting at upper  vent  damper surround casting —- 3 rd one , the stoves  are big $ — door jams then . Good looking but junk 

 all or nothing design is crap too on that door  — NOT buying another . 
So experimented with a fixed slit — about 3/8 wide is perfect balance . Most hot gas still goes out  bottom , when hot , slit helps lighting air flow . Wood use better than before!!
So forced  it to stay   there , used SS tie wire,   then used “ firebrick mortar”  . Filled in all
around flap maybe 1 ” thick  . Unbelievably  good  stuff rated to like 1000 degrees , can buy at Amazon two bags come . Very critucal to mix ratio .
too much water you wreck it
So stove  has seen 900 ( accidental over firing )
no cracks in mortar gets red even 
That would fix rams  stronger than aluminum ,       cures hard as a rock Put in like the epoxy  ?
