Dual quad manifold

That why old timers were telling me two 600's are too much, that really I should use two 400 carters but those are pretty hard to find.

Me thought it be too small so I went with 500 cfm carbs. With a 3,000 stall and 3.91 gears, I found I didn't need those air secondary doors. First I removed the front carb air door and lighten up the rear car door but then later on I removed the rear carb door as well and I lengthen the accel pump shots

Only if I punch it very quickly at lower rpms do I get a bog--or in the wrong gear, like 3rd gear at 55 mph. If I come down on the gas slow but steady and allow the speed to increase, then by 65 or so it can go wot....at 80 on the E way its got more punch then your normal 750 holley DP, IMO..you can punch the throttle as fast as you please

My carbs are hook 1 to 1.

Before it got the 3,000 stall converter, having the carbs 1 to 1 made for hard-too hard part throttle shifts--chirping the tires on every shift is asking for problems, lol With the higher stall speed it soften the shifts and allowed me to run the carbs 1 to 1

I didn't like having the carbs hook progressilty, it was like a single carb, either not enough power or too much power...there be a soft spot part throttle and if you kept on squeezing the gas, it come on too strong and your going 60 in a 45 zone

Now pulling out in traffic is a breeze, I can throttle it to give just enough power as it needs to merger smoothly with traffic.

Best part is 3 full seasons now and I had no problems with the carbs--well once it did start idling a little rough but must have been some dirt cause the problem went away on its own. If the carb does get dirty, its only effects 1 carb so the problem isn't as bad
