i recently finished up my project on my 76 W200 318 of swapping out the old 2bbl carb and manifold for the edelbrock performer manifold and 1406 electric choke 600cfm carb.

the primary reason to prompt this project was that the 2bbl holley was in bad shape and i had serious hesitation problems and i had to ride the clutch to take off. it was getting both irritating and dangerous. plus i was getting 8mpg. my last 3 vehicles had these POS carbs and i l;iked none of them. anyways...

the end result was that the hesitation was gone, seems to have more torque(couldnt dog the 2bbl at all) and throttle respnse was excellent. low speed operation is 1000% better. off the line performance is superb. so all in all it cured the poor response and performance of the 2bb but id arbitrarily guess i gained in the neighborhood of 10hp. but granted i didnt expect to be exactly smokin the tires afterwards. so if a major power gain is your goal this maybe the wrong project as it cost me in the end around $600, but then again i replaced everything including hoses, thermostat, air filter etc. but i would recommend it for better runnignvehicle. i also suspect this is a mod more fit for larger engines which can better utilize more cfm. plus im still running single exhaust.

as for the project itself, it is pretty easy for the most part but every vehicle is different. my 318 is pretty bare as far as wires and hoses go so that made it easier. make sure you do the research before hand though. there are some setups it wont work for. id recommend ordering all the necessary parts such as gaskets and sealants well in advance. i experienced some delays mid project because the parts stores didnt have the needed parts that i was missing. also if you are running an egr now, make sure you get the egr equipped manifold. problems will occur otherwise and the parts store will try to tell you otherwise. if you have any questions let me know, i just got done so the procedure is fresh in my mind. -ryan

I also have the Edelbrock 1406 carb. I love it. I have installed the off road needle and seat kit, and it has helped out a lot on the flooding due to bouncing on the trail. It is a great street carb, and does pretty well off road. If you don't plan on rock crawling, or hill climbing at low speeds, then you should be fine. It used to flood pretty easy when it was at angles, but Bose318 and I messed with the mixture and it hasn't stalled on a hill since.

I would say that this carb is great. If you plan on doing much off roading, I recommend installing the off road needle and seat kit.

Sounds about right. It was really easy to put in. I had never ever worked with a carb before, other than idle and stuff like that, but I had no problem putting it in.
