distributor rotation big block olds
 
I have gotten a lot of very useful information from this site, however everyone needs to take what they read with a grain of salt. I have been a Chrysler guy all my life and that's why I got on here when I purchased my 442. everything that I have seen on here and in other literature says that distributor rotation is clockwise on a 455. now mine is a 75 model but rotation is definitely counterclockwise!

All Olds motors to at least 1964 are counterclockwise (260, 307, 330, 350, 400, 425, 455).

Others better versed in the older models can comment on the 394, etc. - I'm not familiar with those.

Incidentally, where did you read that it was clockwise? Everything I've seen on line correctly says that it is counterclockwise.

I don't remember, its been some time back. My Chilton's even says in print that rotation is clockwise, but the illustrations show timing to be counterclockwise! Lol seriously, a Chilton's on cutlass!

I just looked in my 1975 Chiltons and it shows Counter clockwise.
The only thing I see clockwise is a pic of a 1975 Omaga engine that has the dist in the front so that must be a Buick engine pic.

The crankshaft rotates clockwise when viewed from the front but the distributor rotor turns counter-clockwise.
If I'm not mistaken most all American V8 crankshafts rotate clockwise when viewed from the front. Firing orders are different but rotation remains constant.

Most engines that I know of period rotate that way Trip. The exception would be most Hondas, save the last few years.

Interestingly, those Hondas are mounted "backwards" in the car. Nearly all transverse FWD cars have the "front" of the engine on the passenger side and the flywheel on the driver's side. Until recently, Honda's were the other way around, with the flywheel on the passenger side.
