Need Specs for 66mm CCW crank
 

I bought a used 66mm Counter weighted crank
It looks really good and its supposed to be standard/standard
I want to verify all of the journals are in spec

all of the journals on my crank (yes all 8 of them) were 56.9849
(well one was 56.9845)

my little white factory spec book is from a 67S
but I'm hearing that there is an early and also a late 66mm crank
or at least an early and late specification

my intention is to build a 2.0 on a 7R case, but I had no idea there were 2 different 66mm cranks

so the questions are:

1) what is the #8 main journal spec supposed to be?
2) is this the same spec for both early and late 66mm cranks?
3) can either style of 66mm crank (early/late) be used in the 1973.5 7R case with the small spigots?

I found this thread and response from John indicating it was the late specs

#8 is the pulley end.
your spec is correct
it will fit the 2.4case

Jeff is this you?
thanks for the help

56. #1-7
30. #8

yup me

Brant, The only difference in the 66mm cranks is, non-counter weighted and countered weighted. I'm 99% sure all the specs. are the same from 1965 to 1971 for the standard production cars. I just put a 66 CW crank in my 1975 7R case engine and used the same #8 bearing.
PS...Your 901 slider went out Friday via US Postal Service.
