Default FiTech Fuel Injection timing control question

I am thinking of dumping the carb on my 350 and installing a FiTech injection system. I would like to utilise their timing control feature but am advised that the Pertronix module I have in the standard distributor cannot be used to send a signal to their unit and I need a magnetic pickup only. Does anyone have any suggestions as to what magnetic pickup would be suitable? Don't really want to have to shell out for a complete MSD unit or the like, they cost around a grand here.

I recently bought and installed a holley sniper fuel injection and matching holley distributor. I chose holley because they seem to be selling more than fitech or msd resulting in more individual forum posts and better support from other owners.
I am happy with the results because it works great. At least 50hp gain over my tired carb and hei.
As I understand it a different pick up is usually required for computerized timing control because of electro magnetic noise on the line from distributor to fi computer. Why a shielded cable would not allow for use of hei pick up I am not sure.
There is a youtube channel called turbo camarro. He made a video about modifying an hei for use with holley sniper in order to avoid buying the new distributor. I wanted to follow his instructions but ended up just buying the complete holley dist, coil and box. Im glad I did. I can cold start my 77 and immediately back out of an inclined driveway with no hesitation or surges. Idle cruise and wot all work great.

I'm using timing control with my Fitech, I picked up an older secondhand MSD dizzy/coil/6al for cheap before I built it, so never tried to get it to work with the stock ignition. Have a look, you may be surprised at how cheaply MSD stuff can be picked up secondhand, and based on my and a few others recent experience I believe the quality has gone downhill on new MSD stuff in the last couple of years anyway. If buying new I would probably buy ICE ignition instead.

I may have a different view than others. Im using newer msd distributor, 6al, coil, with the Fitech 600, and utilizing the timing control. MSD still builds quality stuff, Ive used MSD parts since 1980. Anyhow, it works pretty darn well. My suggestion would be to install the whatever fuel injection system you choose, get it running, then switch to a timing control if so desired. I had issues trying to run timing control when I did my initial installation. Tech support suggested I use a basic setup using the traditional vacuum advance which we are familiar with. I did and was quite happy with the results. Now I knew a bit about the fItech. When I installed the 434 sb I switched to timing control. I set the initial around 15btdc and drove it that way for a week or so before taking it to a tuner and having it chasis dyno tuned. My exhaust is still too small for the engine but 455 rwhp and 440 ft lbs torque is a real kick in the butt. New headers are on the wall in the garage, just need to build a 3" exhaust for the 500 rwhp the engine is capaable of.

If you are go for Fitech, then buy the 600hp kit, with ignition control, not the 400 hp with out.

Thx,
John

P.S Sunstroked again thanks for the deal, I love my 8572 :- )

You should be able to use a standard gm hei distributor. and run the fitech timing control with it. I have the fitech fuel injection on my engine with a gm hei. but im not using timing control. but pretty sure you can use it.

Because I have a mechanical tach (recently renewed) I wanted to stick with the original distributor (also rebuilt a few years back but not many miles on it) so at this stage FI is looking like a too hard basket or rather too expensive option to me. Seems to get where I want I will need to run the existing ignition setup which I'm not entirely happy with because it won't give me the equivalent of manifold vacuum advance under 1500 rpm.
Tach conversion would run me to $500 here, MSD ignition $1000, FiTech 600 hp system $2,000, Fuel command centre $850, vent lines etc another $200 odd. It would make more sense to do an LS conversion $4800 here for second hand motor, wiring harness and computer.

just get a tach drive distributor like in the ebay link. and don't use the timing control on the fitech. it a easy setup. I am running the same distributor and fitech. it runs great and im getting 17 miles per gallon. with a 450 hp 383.i also used the fitech inline fuel pump kit with line and everything needed in kit. the fitech 600hp system is only $1000.00 I also used the stock fuel and vent lines on my 71 only cost around $1400.00 for everything.

I used an HEI distributor without module simply to trigger an MSD 6 box and MSD canister coil. Then connected hi-tension from canister coil to an MSD adapter in place of deleted OE HEI coil then HEI to distribute hi-tension thru sp wires.

Maybe you can use an HEI without module to trigger FiTech?

-edit- maybe you can delete just the pertronix module but retain its pickup to trigger your FiTech?

It would be interesting to find out if the HEI can be adapted to connect to the FiTech. I don't believe that the Pertronix can be adapted as it is an all one module.
