Th350/Th400 - 258mm (10 1/4") Converter
This converter is based off the 245mm diameter, so we have several stall speed options. It is fully furnace brazed and hand tig welded for extreme durability. We use a custom CNC billet front that will fit ANY GM engine/flexplate combination you can dream up. Select standard pilot length for SBC/BBC/99-00 4.8 and 6.0 long crank, or extended length for LS engines.
Available in stall speeds from 3200-4600 rpm
PLEASE SPECIFY FOR LS ENGINES.
