Hemi 6 245 & 265 Crates

(and the only automatic that bolts to them is a cruddy BorgWarner BW35).

Some rare Hemi 6 had the Torquefilte bolt paten but you will pay big dollars.
Castlemaine Rod Shop in Oz have a snadwich plate to fit borwaner bolt paten to Torqueflite.

The R/T Chragers had a factory 305HP & cut the 1/4 in 13.9s , I have seen NA ones at 400FWHP
