Yes, the pick up is in a different position.

Make sure the firing sequence matches the rotation of the distributor. You can confirm this by pulling the cap and seeing the rotation and them make sure your wires are set up for this rotation. NOTE – this is for the 351 WINDSOR (NOT Cleveland) – Standard firing order is 1-3-7-2-6-5-4-8 the RR firing order is 1-8-4-5-6-2-7-3.

Just finish a 1976 351 winsor ford. It won’t fire up, I have tried all firing orders for a ford and nothing. One thing l am unsure of is the crank and distributor turn clockwise, this engine is the rr. Is there a special firing order for this application. What should l do.

Thanks for the input. Changed starboard engine starter to clockwise starter and everything worked as it shouldplus engine started, until a push rod bent. Now have to figure out if reverse cranking would have contributedto engine issue. O joy!

If it is a reverse rotation engine, then you need a reverse rotation starter.

Perhaps. If you typicaly see oil pressure during cranking (not starting) AND the replacement starter was MUCH slower; then you might see an issue with oil pressure not picking up. My guess is that if the motor seems to be turning at the same rate with a new starter, then you have an issue with the oil pressure system (wire or sensor).

Also relative to the Bertram, would the incorrect starter cause oil pressure to not pick up during rotation

I have a 1985 Bertram with Mercruiser 270 engines. The mechanic put identical counterclockwise starters on both engines. The rotor on the port engine turns clockwise and the engine runs great. The starboard engine rotor turns CCW and despite new plugs, fuel supply good, good coil and distributor pickup, rotor etc (worked fine on port engine). Compression is good on six of eight cylinders. At a loss to explain lack of firing in any cylinders unless starter is wrong. Should starboard starter be clockwise rotation or counterclockwise starter?

Do a compression test to see if the timing chain has jumped a tooth – that is the most likely situation.
