Carb Choice

Being I am building this to just cruise around and I will be spending a lot of time just driving in the 40 to 70 MPH range, I want to occasionally be able to get her to really jump. Last 360 motor I had with the 750 vacuum, it would actually bog down when I mashed the gas? I was told that was the secondaries looking for the vacuum, and I should get a mechanical secondary carb for the stroker??? Did I not have the vacuum carb set up correctly?? Also, being that this will be a cruiser, what would be a safe torque converter so I get full lock up while cruising without slippage and heating up the tranny? My guy is looking at about 2800 but I had other opinions of about 2400?

Great additional info, Thanks. After rethinking the situation and trying not to stray too far from the original question, here are my thoughts......Very few as delivered/out of the box carbs are ever optimal for the exact combo the are bolted to. After initial setup tuning, many will need tweaks in the jetting, pump nozzle or power valve and in some cases (vac secd) opening rate tuning. Patients with some trial and error is often needed depending on the individual case. Once some have had a vac secd that wasn't right it sours them on that type carb. Could it have been corrected? Most likely yes. As far as what you have now.......With the choices you've presented, and plenty of torque available, I would choose the DP. With a converter built/recommended by a good shop (PTC, Dynamic, etc.) you'll get stocker type drivability and the ability to flash 2500-3500 rpm's when you need it. With a must have optimal timing curve, meaning as much initial as you can run, i think you'll quickly learn to be able to cruise normally and keep your foot out of the secondaries and when you do want them, there will be know doubt you'll have them. Sorry for the long winded response :icon_smi:.
