Distributor replacement.

[Kmac]

Anyone replace their stock plastic distributor with a MSD street fighter? If so, did it solve any mis fire problems and improve performance? Thanks

Anything MSD is going to be better than stock and unless your stock dissy is the cause for the misfire it probably wont fix the issue however usually when somebody upgrades to an MSD dissy they also upgrade everything else also which probably would fix a misfire.

I wouldn't be so sure about that...

Granted I have no experience with MSD products that fit these trucks, but I do have a friend who has some with their OptiSpark distributor for 90's F-bodies. That thing is complete garbage. Had to replace it after about three months. He put an ACDelco on the car and never had another issue.

I've read that MSD products are not what they used to be, but take that for what it's worth. Personally I'd stick to ACDelco.

I will not use MSD. I used one of their coils in my TBI burn. Original GM coil had 100k on it. The MSD lasted 20k before it **** the bed and gave me all sorts of headaches that mimicked a bad ICM.

I would suggest looking at United Motor Products part number 9362 . Rock auto carries them and they are Half the cost of ^these^ guys. These are also made in the good ole USA .

Yeah, no need to spend big bucks on a Vortec replacement distributor. All of 'em are gonna be Chinese crap. Get one at a decent price and chuck the cap, put a quality cap on it. The lesser quality Vortec caps are bad about developing internal crossfires that will drive you nuts trying to troubleshoot.

And I absolutely agree with disregarding the MSD product altogether.

That's why I thought too on my 94 Tbi. Brand new dizzy did not run right, exchanged it ran better but not quite right so I added a cap/rotor from AC Delco and it ran ballsy for a week. Then it started acting up. Had good power at start up then after warm up lost power but sometimes runs ok. So my suggestion stay with Delco or Delphi whichever is cheaper.

I went with this one. I will see how it does. has a lifetime warranty.

I had a bad gear, which is why I had to replace. There are many things that can cause a misfire condition
