<DIV>Steven,</DIV>
<DIV>Thanks for the reponse. I don't think I understand (Fabricate sealed ducts
from the stock body intake to the carbs). Would you be willing to explain more
in depth?</DIV>
<DIV>Thanks,</DIV>

<DIV><BR></DIV>DavidG=> I believe that my carbs are not getting enough air
at higher <BR>=> rpms and maybe at low too. ... How do I get more air into
the <BR>=> engine compartment correctly?<BR><BR>It's unlikely that air
volume is the problem -- the pistons pull the same displacement under any
conditions -- but you could easily have a problem with air temperature. If
you're pulling air only from the engine compartment, it's certainly hotter
than it should be, making the air less dense and reducing oxygen content. The
correct way is to draw all intake air from outside the car, as in the stock
arrangement. Fabricate sealed ducts from the stock body intake to the carbs.
