Brand new 351M need an expert for help lots of questions.

I installed a brand new 351M in my 1977 Thunderbird town landau. I bought this engine about nine months ago, installed it and never got it running right, thought that it might have been a vacuum leak but never really traced it down cause I was going to replace the intake and carburetor anyhow. So I did replace them with an Edelbrock performer 400 intake and an 750cfm 4bbl Edelbrock carburetor. As it sits now, those parts are installed but nothing is hooked up on the carb. I had to take off the distributor to install the intake and stabbed it in just to keep it airtight. I was told to get an aggressive cam for the carb or ill just flood it. I just need some guidance on what to do with it. I also bought a full set of Comp Cams push rods, Edelbrock valve springs, and a few dress up parts. I have real down to earth expectations for this car, not wanting it to be a track car, just one with a roar under the hood, and a good takeoff. Any help would be greatly appreciated, Thanks-Chris -aka-ThunderChicken

that particular carb will drown a motor. a 600 is probably better if you want to drive this car sensible at times. here is what you need to hook it up.

That engine has pitifully low compression.
I recommend a 4x4 cam from CompCams as a maximum.

I'd use a 600 Edelbrock,
(or a 600 vacuum secondary Holley).

Of course you will need a full distributor timing curve done.
