My timing is not stable with the wire unhooked. It's not moving more than a degree or so but it bounces. The LO3 has about 90k on it so I'm wanting to do a timing set and new distributor.

I see a lot of issues with the MSD and Accel. I was wondering what the consensus was on a good replacement distributor.

 

I have Genuine GM (New Old Stock) Delco Remy Made in the U.S.A. complete distributor assemblies. They are small cap external coil computer controlled HEI distributors. They are the real deal Delco Remy. GM part no. 1104096 complete distributor assemblies from the GM melonized steel distributor gear to the Delco Remy distributor cap and everything in between Genuine GM including the Ignition Control Module.

$245 shipped in the USA to the lower 48 states. Paypal accepted. If you are running the stock 89 L03 in your Camaro RS I'll also throw in a set of 8 genuine NGK 6630 UR4 sparkplugs.

PM me for details if needed.

 

If your timing is stable within one degree, I think you're in decent shape as-is. At least inspect that distributor before scrapping it.

IF (big IF) the housing including the bushings and the gear at the bottom is in good condition, it could be that there's nothing wrong with what you have--or what is wrong is fixable with some fresh parts.

I needed a mainshaft in mine; it's common for the magnet near the pickup coil to crack. Amazon has mainshafts for about $140.

It might be that you've got a partially-failed module.

If you insist on replacement, a new or "used-but-usable" Genuine GM "Delco" distributor would be the way to go. The Chinese knockoffs even from the "big" brand names generally have poor modules and questionable overall quality.

 

You will be about the same place with a new distributor.

 

What makes you say that? This is the first time I've played with TBI. My other engines have always been really stable.
