1st off, forced induction and fuel injection is my realm of experience. I now have an 82 ram truckwith a 440 swapped,727, 3.23's.
Motor is 10:1, long tubes. just removed 906 heads and installed an off brand set of new aluminum 210cc heads that were stripped of all the junk valve train and replaced with better valves, springs,etc,,, heights were set, pressures etc. Engine has a purple cam, Mopar aluminum intake, msd pro billet & coil and for whatever reason a pile of **** carter 625. Since swapping the heads( which is all I've done since getting the vehicle), runs horrible until you get up into rpms. I've been quietly researching here and seems an 850 is the way to go. Thinking probably a quick fuel carb. I would like to set it up myself but I have no idea where to even start with the jetting, squirters, , cams, etc. Would like direction to a thread or some sound advise on a good starting point as I don't know what the motors like. Also, ifeel the msd has got to go unless I can tune it for street use. It is now as it came out of the box but have never setup a mechanical advance dist. Advise? Sorry for the long post
