mercoupe ! It is an Edelbrock 257. I removed the "evidence by grinding it off both sides and media blasting it so it would look "stock" even tho the area between the carbs were of a different design on the 1956. I also knew the 257 's rear carb was a little bit farther forward that the one from Ford and was not sure on the Edel 255 and I wanted to run the carbs progressive and it they work find. I port matched the 56 heads with a slight taper for the first 1/4"-3/8"; from old experience that helps velocity.
Gremlins popped up when driving it the first time. Seems like carbs with vacuum secondaries like the Fords work different than the Carters mechanical linkage. The photo shows a 1/4-20 bolt and nut in the stock linkage and I needed to back off the auto trans pressure rod to make it shift proper. I'm not sure what the stock stick shift linkage looks like but the auto trans one has a lot of "monkey motion" which I guess moves when the vacuum secondaries open and it allows the trans to down shift. As I accelerate from a stop it will shift a 17-20 mph normally and if I get on it a little it shifts at 40-45 and a little firmer so I'm happy with that.
A change is coming as I wanted 2 identical WCFB's but as the photo shows the linkage better they are not. I have however just recieved a NOS WCFB 2080s which is an exact match to the front one. It came in the original Carter box with instructions printed in 1953. They do not come with mixture screws so I'm waiting for them to make the swap. I will install it on the front to make sure it works fine then put it on the rear. I need to check out all the gaskets and the accelerator pump and make put in one for todays gasoline.
I drove the car to my favorite cruise spot Saturday morning (Donut Derelicts) in Huntington Beach and had many questions and lookers. Not to many 1956 Ford NASCAR setups in So Cal...................JD
