Well guys I said it could be done, and here it is...
Opti cam sensor (http://www.hughlett.net/Cam%20sensor.jpg)
Opti cam sensor 2 (http://www.hughlett.net/Cam%20sensor2.jpg)
Cam sensor plate (http://www.hughlett.net/Cam%20sensor%20plate.jpg)
Backside of cam sensor plate (http://www.hughlett.net/Cam%20sensor%20backside.jpg)
Cam sensor shaft (http://www.hughlett.net/Cam%20sensor%20shaft.jpg)
I used the existing opti, milled down the legs for the bearing retainer plate which is now built into the aluminum plate, turned a billet piece of aluminum to fit perfectly inside the housing and drilled and tapped it for a pickup sensor. Then I sacrificed a distributor that the sensor came out of and cut the shaft off that held the pickup, trued it up on the lathe leaving a dowel that fit directly inside the existing untouched Opti shaft which centered and trued it, then I tig welded them together.
The plate is fully adjustable 360 degs. And is held in place by a set screw that just holds the plate from turning until you get the billet aluminum cover on that clamps it firmly down into place. (I'm in the process of making it) I will update this page with more pictures when its done.
For those of you that don't know, this setup is for aftermarket sequential engine management systems such as the F.A.S.T. system like I am using. you will no longer have any use of the opti except for the cam sensor itself, which means you will have to use individual coil packs and somehting like the E-dist from FAST, or the MSD CPC system. I know this is not for everybody, but seeing as how so many people are ditching the Opticrap now I thought I would share this with you. There are alternate ways of doing cam sensors, but they involve allot of machining inside and on the timing cover and timing set, or the intake manifold if your using the dist. plug from MSD. (if you can get one). My way requires no modding to the engine itself, is fully adjustable from the outside, and can very easily be removed if needed.
