I'm looking to go from an Edelbrock 800 to a 4150 type Holley.
The rundown on the car and combo is a 67 Belvedere, 727, 451 with Edelbrock heads ootb, RPM intake, 10.5 comp, .520-254 solid cam, 9.5 converter, 4:10. This is street car but not interested in an electric choke as I have never used one being in Phoenix. If I decide to go that route it seems this time of year is as about as cheap as I am going find prices.
What carb would you guys recommend here?

On your deal a 850 to 1050 CFM double pumper 4150 HP carb. is what I would buy, maybe a similar Quick Fuel or one of your other favorite brand carbs. EFI with a single 1000 to 1250 CFM 4150 throttle body is as good or a tiny bit better (and not compatable (SP?) with the dual plane intake you have) but a lot more money to start with

The Holley 850DP is calibrated as a track carb. It will be very fat for a street car OOTB.
If you are comfortable with tuning the cruise and transitions, it would work for your application.
Master, again and still

You might want to think EFI I agree. Something like a Sniper or the MSD Atomic for a car like that. If you insist on a carb then I'd highly recommend something with billet metering blocks so you have a fighting chance at tuning it. The problem there is the better carbs with the latest features (idle air adjust, billet metering blocks, clear sight glass, etc.) are expensive. The really good carbs are close to $1000 and you still have to spend a few weekends with a screwdriver and a wide band to tune them.......

I know this isn't a street carb but I'm going to buy a 750 for my little Ford, I've had great success with the 950 e-85 version on my Mopar. The shop that does my dyno work has been selling quite a few of them after working on mine. https://www.summitracing.com/parts/hly-0-80804hbxAnd yes the gass carbs are usually set up fat.
Have a great day Iowan

What carb would you guys recommend here? Any of the billet block/base-plate carbs can be dialed in easy enuff especially if you have a wide-band afr gauge...........I`d stay clear of Holley personally and go QF, Pro-form etc. but I prefer and build from BLP parts and at a minimum a cast alum. main body OR step up to a full boogie billet........... EFI.........

OP combo is almost identical to mine. I ran an 830 DP for years with pretty good success. Last year I switched to a Holley 1000 HP Annular Booster carb. Every aspect of the way the car ran improved, both street and strip, with the exception of gas mileage. I don't really keep track of mileage, but I feel as though it was a notable difference in the "less MPG” direction. No question however that the cars throttle response improved. I attributed this primarily to the Annular boosters. At the track, which I'm primarily concerned with, I gained 2 tenths
I felt pretty good about my choice and results.
