I have the 800 cfm Edelbrock Thunder Series on my mild 440 for the past three seasons. No complaints. Adjusted mixture screws and good to go...no off idle stumble for me..

3310 and 3310-1 are diff as they have a front and rear metering block they are 780 cfm !
3310 -2 and later are 750 cfm !
yes they have diff jetting but both work very good .
i have i friend that has dynoded his 340 and no jet changes it was right on !
Most of the time spent on the dyno is at WOT. And nearly all of the Holleys that I have had have been right on or very close at WOT. But the problem areas are in the transitions and cruise. Those areas are typically not measured on a dyno, but are where our street cars spend nearly all their time. Once again, the 3310s and the like are good carbs. They just need a good amount of work to be right for our street cars. Just because they don't exhibit any bad habits does not mean they are dialed in. I still occasionally pick up a used 3310 at a swap meet for $75 or so, clean it up, and throw some gaskets and a couple other parts in it for a buddy on a tight budget. But then it still needs a few hours spent on it with the wide band to get right. I don't usually charge them for the time I spend so it is a good deal for them. But a new Street Demon with it's modern features makes a bunch more sense for $350+/- than redoing an old 3310 for $125+/- and the better part of a day in labor. There are simply better carb choices available today for our street cars than the old 3310s.
Master, again and still

I've been eyeing the Street Demon for the Imp. It has a really mild cam (touch over stock Magnum cam). Honestly, it's been tempting to find a good low rise spread bore intake and drop a reman TQ on it more for that nostalgic sound than anything else.
My old CarterBrocks have been used up and modified in various ways over the decades and I was never entirely happy with the carb that was on the car. A Street Demon is likely going to sit on that old CH4B and do the deed until I convert to port EFI.
FiTech has been in my eye over the last couple years but I'd prefer going port EFI again. Sadly, the EFI intake from the TT440 will not clear the hood on the Imperial so I'll need to find another solution when that day comes.
I've dealt with various TQ, Holley and AFB carbs over the last 30 years. The AFBs always gave me better street manners and mpg but the Holley carbs usually delivered a wee bit more power at WOT.

750 DP. Buy a used one on ebay and a rebuild kit. A DP is not the best idea for a mild street engine. He would be far better off with a vacuum secondary carb.

This, and pretty much everything else DaveR23 has said in this thread. The 3310 was a marginally adequate universal carb in the 1970s. I still have a couple. The "original" 3310-1 that I have is kinda cool because it has the higher flow with the normal downleg booster in the secondaries, and a secondary metering block. Still cannot imagine ever using it on anything. A long time ago, I did a lot of tuning and track testing between a 3310 and the original Carter 4327 on my stock ish 440. There was nothing better about the 3310, and the Carter was faster.

Alot of great recommendations here but the Street Demon was designed by a fella who worked for Carter back in the day. His design incorporates the best attributes from the great STREET carbs of the day- the Carter Thermoquad, AFB and the Rochester Quadrajet. So the Street Demon gets my vote here.
Keep old mopars alive.

hi you did not say what purple cam ?
we can only guess this is for street use ?
with that limited info get a 3310 holley .
easy to tune , parts , gaskets avaliable every where !
easy peasy ! I too would like more information as well. Auto or manual trans? Rear gearing? Headers and exhaust? Which car is the engine in?
The beginning of knowledge is the fear of GOD.

I have a 750 Street Demon on my 74 Jensen Interceptor with a 78 New Yorker motor in it. The carb was too rich on cruise but after a dyno tune that changed just the rods, it was fine. When I rebuild the original motor properly, I think the 750 will be about right. If they made new bowls for the big TQ I would put it back on. Love the howl. Look at Page Four.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
