Chrysler 360 w/ W2 Econo Heads, Headers, 30.over

WOW! Lot's of options here thanks everybody!

GTXperience: My concern was that I think I can get a smoother ride around town, then the 4150
750 cfm Holley that I'm running now. I guess my real question is what is everybody else running?
And I know mullinax95 love's his (I'm guessing it's smooth throughout the whole range of gears)
So either, my Holley really is great and needs some adjustments from a pro or I need to get
as LXguy put it a 770 street avenger. What I'm really trying to say is what is the best carb
for the mileage and cruising ratio in you alls opinion? Like LXguy said, ttinkering may not help.
And Yes, I have no choke.

Mullinax95: Can you explain the love for your Holley 4150? I'm being serious here. Efi sounds really cool. I'll
probably wait to see a car with it before attempting the conversion. The motor part is not going to happen, because
this is a new engine built by a reputable shop and I'm keepin her.

Stroked340: Thanks for the opinion, but I think I'm getting away from the street strip idea, although I think I'm
in way over my head already with the setup as it is.

Rockin Ronnie: Thanks for the gear ratio tip, I've heard of that before and thanks for the long explanation...I need that.
Also, I'll do some lookin into the Edelbrock 600 SP!

1qwikScamp: That's exactly what I wanted to hear (CRISP) because my car starting out is anything but. What exact model
number metering block did you buy? I think I'll go with blue anodized :) Also, I totally agree with having to extend
the fuel lines, I envisioned that already. I really think this is my best approach before I get drastic! Thanks.

Mullinax95: What do you mean standard or adjustable? I saw these on Muscle Car TV and they looked adjustable, but didn't say which model it was.

And let me add one more thing: Isn't the idea of the carb suppose to match the air fuel ratio? I've seen these guys on Dyno's maxing out and tuning the carb, so is everybody here going off luck, experience, or real pen and paper facts? I suppose most of these carbs are adjustable enough to handle different setups. How would I know to decide between a 570,670,770 and so on, with my type of driving application in mind. Thanks! I know long post...sorry.
