Rpm drop between gears "feels right", unlike the factory pick up overdrive I ran before, maybe because of the lack of a granny first gear?
Hemi box to Passon OD box ratio comparison:
1st H 2.65 : 1,
POD 2.66 : 1
2nd H 1.93 : 1,
POD 1.59 : 1
3rd H 1.39 : 1,
POD 1.00 : 1
4th H 1.00 : 1,
POD .80 : 1

As for camshaft, I tried to source one slightly larger than a factory sixpack cam:

INT .470" EXH .504"
214 223
112
