cool bean man..i spent about 20 hrs now reading up on the 3 circuit carbs, i understand them more now i was just not sure which one where which...mine is stock from holey and looks like it is super rich from them so i have a lot of tuning to do

There are plenty of posts about tuning these 3 circuit doms on here and on the sponsored 460 website. I'm running a 1250 on my stroker and run it on the street. I have no trans brake. I did the poor man's tune up on mine that drastically solved my issues which were stalling out when lifting after the burnout and loading up terrible cruising. I removed the intermediate bleeds entirely and swapped them into the idle bleed's spots. Not very scientific but it worked wonders for me... and a pal followed suit on his 496ci BBC with similar satisfactory results. His issues were worse. It totally leans out/delays the intermediate circuit which is where my issues were.

At some point I will go further with an air bleed jet kit and dialing it in but for now this trick got me going.

Here's a link to some of the help I received on here with mine. Lots of good advice from this site.

Here is another link from the old site where I first started tuning on it. Lots of the same tuners with good information back then on that site.

how do they work on a street driven car

You need to define - "Street Driven".
Everyday, once a week, Cruise nights, Sundays and legal holidays, to and from car shows, there are all types to be considered "street driven".

decided not to do any street driving

why?

in the summer my girl drives my 72 torino all over ,when ever she wants, as well as of a lot of bb around here with doms on them, she drives it to work,store,etc

Man I'm rolling all over the place on the street with my 3 circuit 1050. After a bunch of frustration I sent it to Competition Carburetion. Bobby got it dialed right in for me and it runs great on the street now.

Even with the overdrive trans it has no problems loading up. If anything it's a tad lean at part throttle.

IMHO it was $$$ very well spent for dependable street manners.

becasue it will have 14-1 compression and 4.56 gears ..etc..etc..

i understand, sounds more like a track car. its funny my stuff starts out as street stuff,and the next thing you know, poof its a race car

so what is with the -2 i found the 8896-1 but not a -2

8896 = original style
8896-1 = HP style
8896-2 = HP style with some calibration change[s]
The -2 model has been in the Holley catalog for several years.

Are you sure that the -2 isn't for two four barrels, seems like Iread that somewhere.

I'm sure the 9375 carb is the 4x2 calibration 1050.

The original #8896 is almost an entirely different carb. It has standard "bar type" boosters, pressed-in air bleeds and a different calibration altogether. The -1 is still the older main body but, having "annular boosters" with a calibration for them. The -2 is the newer type, flat-top main body with "annular boosters" and screw-in air bleeds and again, a different calibration.

Every time there is some design change with a Holley carb it gets the next "dash" number.

Good to know.
