EEC-III conversion to DurasparkII
I have an 83' F250 351w that came out of California. I've been having problems and a mechanic friend from FTE got down to the conclusion that I need to swap out the existing distributor (which was garbage) to an 83' distributor and swap the brown grommet ignition module with the blue grommet module. I went to replace and found that the new distributor, with the vacuum advance (the old was controlled by ECM) had a larger gear than the old. So I went to get a pin punch to swap gears and found out that the original also had a longer shaft that drives the oil pump. Do I need to swap the old longer shaft with the new one or does anyone know if a normal (not high altitude or California) 83' distributor shaft is long enough to engage the oil pump? I'm far from a mechanic so I'm having a hard time with this.
Anyways- 1983 F250 351w 5.8L, originally brown grommet module with a distributor that uses CPS. California truck. Previous owner cut about every emissions wire that led to the control box under the seat anyways.
Any help appreciated.

You mean the new one? Because I have three, one I pulled from a 78' Turino with a 351W and the new one and both are identical. Then there's the third that came with the truck that is controlled by ECM. The problem is I guess I was wondering if there is a large difference in the components in the block Between a 351W from California and a 351W from Washington. Because the gear on the originally installed distributor controlled by ECM is quite a bit smaller. I bought the new one at Shuck's and I specified several times I wanted the 351W distributor. A member of FTE came over and said it was the right one but I needed to swap gears with the original. It's all a little confusing. Maybe I should have cut my teeth on an inline-6??? lol

Sorry for the double post... too late to edit. I compared the 77' drive gear to the original Duraspark III distributor and they have the same size gear. Just different size shafts. I think you may be right in that I was sold a 302 dizzy and the girl didn't know what she was doing. It looks the same in every way but the gears are different sizes, right?

Did a little research and I think this is the distributor you need: http://www.autozone.com/selectedZip,.../selectZip.htm . What I'd do is take the original '83 EEC distributor to Autozone and compare its shaft, housing and gear with the Autozone distributor for the '81 351 Windsor motor.
