This is what used on my 91' the #8366 small Fbody MSD probillet distributor, MSD external coil #8226 and Accel's F body conversion adapter kit #74170. Works great.
Did you notice improvement? I just bought the TPIS Big mouth base, AS&M Large tube runners, and a ported upper plenum. I also have a cam Long tube headers and exhaust. My stock distributor is crumbling on the inside.
This F-Body conversion kit is nice and clean? Just pretty much plug and play?
Just need to know the correct part number for a 91 L98 MSD Distributor part# I am going to upgrade, but can find a straigth answer.
Something you might want to think about if this change in not 100% necessary cause of lack of real estate is when you go with a smaller diameter cap, there is less room between posts. If moisture should collect in the cap, you could experience high speed misses or worse pre-ignition.
I would recommend that you stick with a larger diameter distributer if you have to get an aftermarket one. I was looking into getting one of them a while back with the SR, which is somewhat a tight fit, and decided to stay away from it cause of this reason.

Get the MSD. You will be happy. The above is true and you will find a lot of racecars use a larger cap conversion to prevent the above. With that said most of us here have real streetcars and don't rev to 10,000 rpm so the condition will never happen.
I have been running one for a long time now and would not consider a stock distributor. When you hold one you will see the difference.
For more information you could try http://www.thirdgen.org the guys there for the most part have a strong knowledge base. They may be able to shed some light.
1. Gonna rev past 6500?
Yes: Aftermarket
No: Stock
2. Larger cap is technically better as due to the post issue.
These are what I have gathered so far in my viewing of posts (before the cat fight years of CorvetteForum.com)
So with that knowledge, I will probably go to a stock or similar to stock style and save the extra cash for other mods, as with a SR I don't plan on winding it up too high, and I don't need the "better" aftermarket offerings.
Now I notice you are a 91, so depending on route. I would go stock-ish (possibly upgrade coil and such) if you are using any intakes other than a single plane, mini-ram, lt1 conversion, or stealth ram. If you are still using the TPI, you have a LONG way to go before ignition becomes your limiting power/rpm issue.
I've actually got a small cap HEI MSD probillet for sale that has about one hour or two of runtime..... I went to a magnetic trigger set up... it's a long story. I also have a new coil and the wiring you'll need to go from the large cap dist. to the small cap. PM me if your are interested.
On another note, I know of a lot of fast Camaros, Z28's etc that use their factory small cap and these guys are running equivelant and some faster ET's, wheelies etc, with no issues.
