|egchewy||Ok. This is my "told you so" moment. Called comp cams and rep verified iron gear. I exchanged it today at jegs after work. Thanks everyone who planted seeds of doubt into my head and saving my engine from needing rebuilt.|

so i'm finding it hard to find a 2 wire dizzy w/ an iron gear.
not to start WWIII, but i've had tech support from summit, jegs, and pertronix all tell me that hardened/melonized steel is compatible with a hydraulic flat tappet cam.
maybe steel gear tech has changed over the years.

I called and they confirmed steel, which was what I needed. Said they’d been meaning to get that description fixed.
Side note. Don’t leave the key on without the engine running, it burns out the igniter module in the dizzy. Mine went shortly after I got on the road, pertronix replaced under warranty. I definitely had the key on a lot during the build testing lights and such.

|egchewy||Loud and clear. Will head to jegs tomorrow to return it. Found a nice looking pertronix flame thrower billet 2 wire dizzy with iron gear on their website.|

compatible gear and cam materials
here's what I found from summit's website suggesting that hardened steel is OK w/ iron cam.
here's another site saying the same.
i've also seen other websites saying that hardened steel is not compatible with hydraulic flat tappet cam (iron)

|egchewy||Ok. Decided on a billet style 2 wire dizzy from jegs with hardened steel gear. I was assured this is compatible with my hydraulic flat tappet cam. Planning on letting fitech control timing advance. Does anyone know if the complete kit has a starter relay or do I need to buy one?|

Cons: Cost if you already have a distributor. Not much if buying a distributor anyway. Complexity to get it phased correctly and programmed in software.

I'm running the FiTech 600 hp system and letting it control the timing. I am not using any ignition box and haven't had any problems so far (knock on wood). I'm using a locked out MSD distributor with initial timing set at 14 degrees, with the all in at 34. Once you get it up and running, that's when the fine tuning starts. There are many forums out there like this one that will help with tuning as well as those that won't.

I have your set-up.
Been using a CRANE HI-6 Box and coil for 14 years, no problems. I like the fact you can set rev limit with a small screwdriver.
Was running a Unilite distributor, just switched to a MSD dizzy.

ok...finally ready to purchase a distributor.
been doing lots of research and there seems to be lots of things to consider.
running a 289 with cast flat tappet cam, fitech 600hp efi.
hearing some good things about pertronix and was wondering if the linked distributor would be a good compatible choice for the set up
any input appreciated.
|07-11-2019 09:02 PM|
I run the Fitech 600 with the MSD dist. I let the FiTech control timing and have had no issues. Just be sure the MSD model can be locked out.
MSD85793 dist and MSD84211 adj. rotor
|07-11-2019 07:59 PM|
I'm not sure if it is compatible.
But I agree with MastangMan, Pertronix is a nice system. It gives you all the features without a box. Multi-spark through the whole range, which a lot of boxes don't, and a rev limiter which every Cobra should have.
|07-11-2019 05:12 PM|
|bobl||Something to be aware of. If FItech is controlling timing it has a limit of around 20 degrees of advance. You can program more advance but it can't do it. So you must have enough initial advance to be able to reach the total. IE: To get 38 degrees total advance you would need to set initial at 18. I discovered this on the dyno chasing a low HP problem. Finally put a timing light on it and saw the timing stopped advancing. Subsequently I read some discussion of that issue.|
|07-11-2019 05:00 PM|
I assumed he was wanting to control timing with the FItec which limits your distributor choice. If not controlling timing then the choice is endless.

Yes, certainly determine the proper distributor gear as mentioned above, but as far as ignition, it might help to know what kind of "look" you are aiming for with the engine (period small-block, or lots of billet bling, etc.) and your driving intentions. A street driver doesn't need a fancy "spark box" with a bunch of bells and whistles. For a nice driver I recommend a "ready to run" type distributor with matching coil. No external box, limits the wiring and keeps things clean. MSD, Mallory, and others offer them, but also check out the Pertronix distributor. They have a nice "cast" unit that looks like a vintage Ford distributor but has the electronic module under the cap with rev limiter built in.

Before anyone chimes in about their 15 year old MSD box that works perfectly......Yes, that was before their quality went away.
|07-10-2019 05:28 PM|
Allstar performance makes one that works with the FItech. You will need a phasable rotor available from msd and lock out the mechanical advance.
It uses all the same internals as MSD. It's probably made in China just like all the rest, but at least it doesn't say MSD on it. LOL.
