I dont know if they offer a chain tensioner for the
BB but they do for the SB... I believe that if you
go to the short chain it would be too short... JMO...
I was surprised at how much drag there was when using
the chain tensioner ... I was putting my engine together
a couple of days ago and with just the crank in the
engine I couldnt really measure the torque to turn
the crank(didnt want to get my inch pound torque wrench
out) and I put the cam in and could spin it with
my fingers... as soon as I pulled the pin on the
chain tensioner it went up to about 8# to turn the
crank..... I thought that was ALOT
