I am looking to buy a new carb and i'm not sure on which one I should get.
I was looking at summit new carbs but i'm still wondering if it is a good quality carb. I have been hearing good and bad things about summit products, and this is one has not been out long enough to really get any good reviews. I have two carbs now one thats an edlebrock 600, and one thats an holley 750 part#3110. Tried to rebuild both, but only made things worse. Been trying to get this car on the road for the last 3 months. What I would like to get is the holley 600, but I am a beginner and I am not comfortable with tuning a carb so I would like something that is easy to learn and tune right out off the box with minimal tuning or be able to make baby steps. I do want to bolt an go but be able to tune where I need it . This is on a budget, so I'm trying to not spend to much more money as it will only take me even longer to get it on the road. Who has started of like this and has been successful at tuning the holley 600? This will be a daily driver and I do have a fair amount of mechanical skills, just not with a carb. I have been to a couple of shops but they seem to be in buisness to just make money with no quality envolved.

this is what I have:
350 4blot main .030 bore
10/10 crank polished
speed pro forged pistons
bottom end balanced
.465/.488 Advertised Duration: 282 int./292 exh. Lobe Separation (degrees): 114
Duration at 050 inch Lift: 224 int./234 exh.
edelbrock rpm heads
1.5 aluminum roller rockers
edelbrock rpm intake
50,000 hei coil
th350 stage 2 shift kit 2400 stall
posi 12 bolt w/3.42

I don't race or anything but when I get in, I like to get in go.

Is a 600 good enough?
I was thinking if I go with the holley I would a good performance while driving to work and on the weekends.

I am willing to learn, but it took me 3 yrs to build this car with just manuals and magazines!

I just had the motor redone and I my current carbs are dumping to much gas and i don't want towash my rings.

Any advice would be appreciated!:thumbsup:

Also if you guys have any advice about my combo i'll take it!
thanks steve.

For a daily driver with Holley, I'd go with a 0-80670 670cfm Street Avenger Holley. Electric choke, easy setup.

I've been running a Qjet on the 350 in my Cutlass that has similar specs to what you have there minus the heads. You might want to pick up a book called Super Tuning and Modifying Holley Carbs. Lots of great info in there. The 3310 is one of the easiest Holley carbs to rebuild and tune.

Either one of your carbs will work with some knowledge and tuning. Do some research here on them and go from there. No need to spend huge amounts of money to buy a new carb when what you have will work.

I agree with all the reply's. I was going to suggest the 670 street avenger if you were going to buy. I also thought that you just need your current carb correctly rebuilt or just get it fine tuned. You should go on the carb section here and discribe your carb problems and someone will talk you through it.

For your engine I'd say that a 600, either Eddy or Holley will be a bit smallish. From what I hear, that 670 Holley is easy to mess with, and with a jet kit you'll have that thang purrin and cracklin in no time. Buy one of those, and offset it with the sale of your Eddy 600. :thumbsup:

For a street/driver/performance engine, I don't use anything except a Q-jet. Properly setup, you just can't beat 'um for economy, dependability and good performance.

For a daily driver and on a budget, rebuilding the Eddy is the way to go. The Holley is a good carb ,too, but a 750 is just too big on a 350 as a daily driver. Keep in mind that many problems blamed on the carb are really faults with other parts of the engine.

A Qjet is a great carb if setup right and great for a daily driver.

The 670 Street Avenger is also a nice unit. I went to the Street Avenger from a Qjet ONLY because I know how to properly tune a Holley.
