I am in need of some info on a performance ignition for my 87gt that has recentlty had a carbureted 4.9 transplanted into it. I am finding out that it likes to go through ignition modules. I would like to eliminate this problem and move up to a performance ignition system for it. My question is what would be a good one to go with? accel, mallory, msd?

The most expensive one of course.

For a carb'd engine the best thing to use is the Crane Fireball HI-6R. You basically pull out the module and the only wires inside the distributor go to the pick-up coil.
This also gives you an adjustable rev limiter as well. It plugs right into the Crane PS91 coil.
I mounted the control box in the trunk and the coil on the trunk wall.
Here is the one I used on my 3.4L with a carb:

In this pic you can see the coil right across from the distributor and the harness to the Crane control module which is mount inside the trunk just out of the picture.

Will it work with the hei setup with the coil in the distributor cap, or will i need to go with a different cap and coil combo? I hope the current setup will work, as i just bought an accel hei super coil, and would hate to think i spent the money on a coil i cant use with a performance ignition

Yes, You can use the coil in the cap. The wiring is the same. So in your case you would just have the pick-up coil wires and the wires going to the side of the cap (coil and tach) coming out of the module which you can place anywhere.
NOTE: Just make sure the pick-up wires are not next to the wires for the coil/tach. They must be seperate or the pick-up wires might pick up extra niose. (See instructions with the ignition system.)

Thanks for the info. Do you get much of an ignition "whine" through the stereo with this kind of setup?

No, I have a large system in my car and did not get any static or whine.

summit racing sells a cheap setup that contains rev limiters, nitrous retard, launch control. it also draws less current than msd and accels units(digital)a nd puts out more mj's all for 150 bucks, plus accepts msd style accessories and coils. its a good deal, but having high powered ignitions means u gota replace cap and rotors alot but this isnt much of a problem it works rather well.

Do you have a link?? I just looked on their website and the one you mention is $229. They do have a basic ignition system for $199 but that is the least expensive full kit and it doesn't have any of the optional controls. Both the $199 and the $299 output 1000mj and the Crane is 1,200mj.
