Don't have the hemi curves graphed, but do have the 440 Hi-Po.
This is '67 & below that '68. 0* for the manual cars with CAP.
IIRC '67, both manual and auto non-CAP are 12.5* BTC. CAP auto is 5* and 4 speed is TDC.
I'll try to remember to check the '67 book later to verify.
Woah! big difference there! In 70 the 318's weren't much different between manual and automatic. Here's the automatic specs. 1-6° @ 550 rpm, 8.5-10.5° @ 800 rpm, 12-14° @ 2100 rpm (Distributor degrees @ distributor rpm)
