OK, here goes....
The block and head are both from a '78 Fairmont. The mechanic who rebuilt it put the Loadomatic distributor in and made an adaptor to use the 1100. I used that awhile, then installed a Holley 1946, which is what came on the Fairmont. I used this for about 1 1/2 years with the Loadomatic distributor and had no problems at all, despite what people say about them not working well w/other carbs. Well, about a month ago, I switched back to the 1100 because of choke and idle problems with the 1946. I currently have a Pertronix unit installed in the Loadomatic.
Since I've had the 1100 on it again, I have noticed "flat spots" - I guess you would call them - when you stomp the accelerator. According to Pony Carbs. this is common with the 1100. They claim that they fix it in their rebuild, but I really don't want to take a chance and spend $250-300 just to possibly have it do the same thing.
So...I have decided to go back to a 1.75 carb (haven't decided for sure which one), and I would like to get the right distributor to match. The car will be a daily driver when finished. It's not built for performance, but for driveability, rather. Gas mileage is a factor, also.
