Default Current/former Holley Street Demon users on Pontiac engines. Your experiences?

After finally getting my 65 drivable I'm working on getting it to run right. There is a 750 Street Demon on it now. It runs but not great.

Before going any further please no "throw it in the trash" and "Put a Holley on it" or "Put a QJ on it".

Though ultimately I do believe one of those changes would be needed to "get the most out of it" IF I choose to go in that direction.

Right now I'm interested in getting the Street Demon to run the best it can on the street. There are quite a few big block street Mopar users that seem to like the carb, They rave about the response and drivability.

Searching the archives I see quite a few folks were using the SD at one point I was wondering what your experience was at the end of the day?
  1. Still using it as it was out of the box
  2. Rejetted it
  3. Threw in the trash
  4. Took it off the Pontiac and put it on a small block Camaro

Though 3 and 4 are pretty much the same thing.
