My car busted the TB a while back, and I m putting everything back together. My one concern is this: The cams turn 2:1 with the crank. So does this mean that aligning the cams with the cam locker bar wll be sufficient, or do I need to worry about whether the cams are 180 (or 360? off? Is there really any cause for concern?

edit: Once I get the crank to tdc, it doesn't matter anyway, right?

"Once I get the crank to tdc, it doesn't matter anyway, right?" I concur.

all cams should be a TDC befor you use the lock bar. IIRC, all cam/sprockets have a TDC mark.

"all cam/sprockets have a TDC mark." Not true at all.

but yes, it shouldn't matter whether the cams are at zero or 180.

Crank at 0, cam at 0.
Crank at 180, cam at 90.
Crank at 360 (zero), cam at 180.
Crank at 540, cam at 270.
Crank at 720, cam at 360.
