Okay here is what I have going on.

I plan on running the newest version of MSII.

I have a 1995 LT1 that has been bore'd, stroked and is turboed. Now I want to change over the ignition setup. I am retrofitting on a SBC Single plane intake and plan on stuffing a 1996? MSD vortec distributor (off the pickup trucks) Now I dont know much about it other then it is a 3 wire distributor. Everywhere I look it seems that the ign module is seperate and the coil.

Now with this dizzy do I have to run a crank trigger? I am trying to stay away from this option as it gets pricey and I do drive the car on the street alot.

Currently the motor runs on obd1 pcm with the Opti and doesnt have a crank sensor at all (only 96-97 did)

My friend runs this distributor on his 8 second 6 speed camaro, but runs a FAST setup. Also runs a 7al2 box and a red HVC2 coil. He also has a crank sensor so I need to find out why.

Would I be better off going with a different dizzy? Anyone recommend one I can drop in that doesnt require a seperate crank trigger? Maybe even one that has a ing module and coil already in it?

This setup is in my 1987 Iroc with a T6 74mm Garrett, dyno'd 583RWHP on 8psi pump gas! on the stock pcm setup.

Thanks for any help.

Should i run a 7 wire 1992 camaro 5.7 distributor? seems like an easy solution.

Im thinking this one..MSD-8366

Is it is a conventional distributor driving a conventional ignition setup? Ie self contained?
I has this on my Rover V-8 and this is what I did.
Lock up the centrifugal advance mechanism.. Tips on how to do this in the MegaManual. The MegaSquirt can map the ignition far more accurately. And it already has a MAP sensor.
As regards the trigger it really depends on your distributor. Mine had a VR sensor with the electronics for that bolted to the outside of the distributor. So I first removed those electronics and fed the VR sensor direct to the MS. That worked quite well - bit I've now changed to a hall effect one which I glued to the VR sensor baseplate. This gives a more reliable trigger than the VR one. A suitable sensor is the Allegro ATS682 which only cost a few dollars from Digi-Key.
It's probably not quite so good as going to an EDIS setup or whatever - but a damn sight cheaper and much better than the old mechanical system.

The vortec dist only has a 1x signal. You could not run with only that and no crank trigger.

Run the 92 5.7. It's been done plenty of times and will be an easy solution

So will the 1992 dizzy be fine to run with boost etc? My Timing will be normal driving around (40* timing etc) then in boost it will slowly ramp down to around 17-20* timing depending on boost.

This is a 383 lt1 that will be running 15-20psi. I just don’t wanna toss away 300 bucks on the msd-8366 and it not control it right or something.
