I continue to like Type F. If a TH400 is cooking fluid and someone thinks synthetic is going to be a solution, i bwahahahhaaaaa! can't find the words.
Just cleaned and prepped a Big Car TH400 case and will build it in March, along side the goings through my Switch-Pitch TH400 which has sat since the 4L80 was commissioned.
The TH400 will be avail for anybody wanting to go high 9's or slower Normally Aspirated, and as usual, a low price (like Post 19) and nice clean looking assembly.
