Thanks for looking, guys.
When I started the build sheet decoding process, and constructed the driveshaft table, like Bob, I expected there to be a separate entry for the Hipo with C-4. Then it seems it was ignored again now that I've moved on to the front spring table. Curious...
Richard,
The 1966 manual matches the part numbers from my version, but uses decimal inches instead of fractional?
I've found a reference that suggests there were two types of C-4's used in '66.
Type I with shift ratios of:
First 2.46:1 Second 1.46:1 Third 1.00:1 Reverse 2.20:1
And Type II with shift ratios of:
First 2.40:1 Second 1.47:1 Third 1.00:1 Reverse 2.00:1
I believe that Type I was used on all T, C, and A codes, and wonder if Type II was used on K's? I've been reading here where the internals (valve body for one) were different in the HiPo C-4 and wonder if this resulted in a different set of shift ratios? 4-speeds seemed to differ with a closer ratio used in the Hipo.
