Hey DF, put yer thinkin' cap on..... the OP has a worse low SCR problem than you do in his 318 with what look to be open chamber heads plus piston eyebrows. With that 272 cam his low RPM torque is gonna fall noticeably LOWER than a 225 slant 6. And his altitude is higher than yours... so even worse! I do like the easy ramps on that cam, but wowzer, it would be awfully sluggish starting off.
OP, can you check the head casting PN on your heads? It ought to be a 7 digit number cast on an intake runner, and may well end in '675'.
And can you tell us your transmission info?
