Not true, if you look at a 1989 Distributor rotation for example on a LO5 350 TBI. you will see the distributor rotation is counter clockwise. Looking at the cap where it is square #1 is on the right then #8 next to it on left of square then so on in a counter clockwise rotation. #1 and #8 are positioned toward firewall. Believe this started in 1988. Now on my 1987 LO5 350 it's a clockwise rotation distributor with #1 up front toward front of car with #8 to the right of it and so on in a clockwise rotation. There also seems to be a lot of confusion on rotations of water pumps. My 1987 GMC Jimmy ( full size) LO5 350 was equipped from the factory with a combination serpentine/v belt System with one of the v belts running the water pump. Because the v belt runs the water pump it is a clockwise rotation pump. On 5.7 350 with full serpentine systems they are reverse rotation. If the pulley is of the v design it's a clockwise rotation pump if it's smooth it's a reverse rotation. Belt goes around the circumference of belt like the v belt does it's a clockwise rotation. If the back portion of the belt( serpentine ) contacts against smooth pulley it's reverse rotation.
Clockwise. clock wise. go to boxwrench.net its a very good site on motors

Rotor turns clockwise.
Unless it has a BOP (Buick/Olds/Pontiac) motor such as a 307, rotation will be clockwise.
Rtr. turning clockwise. Rotate distributor counter clockwise to advance timing, clockwise to retard.
Counter clockwise to advance.......clockwise to retard
153624, distributor rotation is clockwise
