I currently run a Predator which will not clear any stock hood.
Many other guys have had good success with Holley 750 annular discharge double pumpers for moderately built motors with 4 speeds, 780 vacuum secondary holleys for auto equipped cars.
For the more radical street strip cars, a 830 annular discharge holley or the new 950 HP series holleys seem to work well.
In my experience the Carter/Edelbrock carbs run OK but do not make as much power as other designs.

On my stuff, I have found even my mild motors are faster with a 950 HP than a 750 dp. Although one member here had better luck with a 750 HP than a 950 HP so that might be a good choice too. I really think, best bang for the buck, if you dont mind not having a choke, the HP series of carbs is almost unbeatable.------------------

70 351c-4V, Boss 351 holley flange alum intake, Motorsport 214/224 @.050 hyd cam, Crane roller rockers, Hooker Comp headers in a 71 Stang, 2.5" exh w/ Flowmaster 2 chambers, wide ratio toploader, 3.89's. Used a 4780 Holley, 800 DP, 75/80 jets. Ran 13.1- 13.3 in a 3500 lb car. That car required very little tuning, and always ran great. Friends of mine refer to it as the "Holy" Holley, as it must be blessed or something.I do have to say it did not like that combo when I had the motor in my 70 Torino GT, even though it had 3.89's, but a C-6 with a stock converter. No high stall, was a pig 'til about 2500. I rejetted, and it was better, but I really needed a 2500-2800 converter in that one......

I have a 351C in my 69 Mach. I have 2v heads with an edelbrock performer I run an edelbrook 600 cfm with and electric choke. The engine ran lean with the stock jets and metering rod. I when up a couple of number and it run very strong. I am very pleased the with the carb.

Just to let you know how much differnce there was on mycar from carb to carb, on a mild 4v headed motor, (stock valves, mild hydro cam, 9.5-1 compression) it ran 7.80's in the 1/8 with the 750 dp. I replaced it with my 950 HP, and still shifting it at 5600 rpm, (the lifters pumped up on anything more than that), it then ran 7.50's. That's 3 tenths in the 1/8 just by changing carbs, that equals around half a second in the qrtr.

i think that you also need to keep things in perspective as to the application of your car and what you have available to you. if you already have a 735cfm, unless you are trying to get an extra .10th at the track, they use the one you got.------------------

I have a mildly built 351c 2 bbl heads, headers, 2 1/2" duals, a 600 cfm vac sec Holley. Mallory coil, pertronix conv., roller fulcrum kit.I ran a best time of 14.9 in the qtr mile.
This was with my old Edelbrock 1407 (600 cfm)
I had hesitation off the line but it ran o.k. up to 5500-5600 rpm. ------------------

dlewis,The 351C in my panel is similar to yours. (It came out of a 71 Torino GT) and when it was in my 65 F100 it ran like hell.I replaced the old carb with a holley 2bbl carb, and was very happy with it. We'll see when the panel is is finally running. I agree with everyone, it depends on what application you have, and what you plan on doing with it. I don't plan on changing a thing with mine, except to upgrade to pertronix and get rid of the points. ------------------

My '66 F-100 has a '71 351C, 2V heads with an Edelbrock F351-2v intake and a Comp Cams RV cam. I'm running a Holley list #3310-1 (the original 780). It's a vacuum secondary carb with only one accelerator pump. #72 jets and 10.5 power valve on the primary side and #76 jets and 8.5 power valve on the secondary side. I'm happy with it.
I also had the same model carb on a stock 351C 4V that came out of a '71 Torino that I put in my '55 panel. I was happy with that. (That's why I looked for another 3310-1 for my '66 pickup.The body style determines the year of your truck. It's a '55 body so it's a '55 F-100. ------------------
