I searched all the threads.
Used the search engines.
Looked in GS.Org
and @ MetroMPG,
& Auto Speed
& CRXMPG
& Google
But could not answer this query;
Which is better, if you are only going to do one,
Upper Grill Block
or
Lower Grill Block?
HHMM
any takers, I welcome and relish any & all discussion and information.
as it stands my plan was to make the lower grill block removable so I could make adjustments according to engine heat.
But,
That is the second time someone has suggested leaving the bottom open for the cooling of parts other than radiator.(not both on this thread).
So that having been tossed into the ring, my new plan for this weekend is to make the lower air dam, and maybe smooth the rear underside.
Thank You,
