For the needs of your particular build, I think the EFIConnection timing cover would be your best choice. You can use that cover with EFIConnections double row timing set that has the CMP reluctor built into it. This cover would give you what you are looking for----Double row chain, CKP sensor, CMP sensor and not affect your stock distributor.
98 GMC RCSB, 5.0, 4L80e, Moser M60, 4.10 gear, Homemade twin turbo w/Junkyard T3 turbos, 24x CNP, 12200411 PCM.
Where can I see this cover/timing set?
EFIConnection's web-site leaves a bit to be desired. They seem to offer many products that aren't listed. A catalog would be ideal.
I've seen their modified Vortec cover that fits GEN I SBCs but it looks like it's simply the Vortec cover with a GEN I flange grafted on?
From my understanding, it still doesn't support a double row timing chain- If it does, they should list that detail on their web-site and they'd get a TON of sales!
I also don't see where where they offer a double row timing chain / reluctor combo?
I will be utilizing the 4x crank reluctor, which I don't think EFIConnection has re-tooled for GEN I / double timing chain applications.
Can you clarify?
There will soon be a SBC / BBC distributor (small cap point style) that has both the '0411 4x crank sensor and the cam sensor. It will Not have provisions for the mechanical tachometer. The above mentioned distributor is patented! Pricing has not been determined. The first production run is scheduled in early 2014. Production runs are currently being quoted.
Will this be a dual pickup distributor (4x and 1x sensors)? Will this be an EFIConnection item?
Sounds like a great idea but unless they sell the components individually, it still won't help with my specific application.
As stubborn as it sounds, I am not giving up my mechanical tach drive.
It looks like the VSS provision that Keisler has on their SS700 trans is for the Ford style analog VSS.
I'm guessing that it will in NO way be compatible with the 12200411 PCM?
If not, I will need to research my options for an in-line VSS with the stock cable-
The problem is that the SS700 doesn't use the threaded GM style speedometer gear adapter (it's just a fitting with an o-ring that is held in place with a clamp like a distributor) so I may need to do some digging...
I see that Dakota Digital makes a model SEN-01-2 VSS that fits Ford (and my SS700) that is an 8K pulse generator-
Can the 12200411 be modified to accept this 8K signal? If so, I'm golden and it's only like $35!
I know that GM had 2K and 4K pulse VSS but what does that equate to in the table you provided above?
Is that 2K or 4K per revolution or per KM or?
Again, I apologize for the dumb question(s) but I do want to learn about all this stuff.
Thank you for your patience!
