Go easy guys, This is the carb that came on my new to me '66 with a BBC in it. Can anyone help give me an idea of what I have here?
In talking with him, he suggested sending to a company (whose name I can't recall) and have them go through it, then send it directly to him and he would set it up on the new motor. That's how this got started.If you are looking at a VortecPro engine I would suggest getting Mark to supply you with a new carb set up for that engine as well as a distributor, then just drop it in the car and go. That carb you got there has been cobbled together by the looks of it.
I bet I can remember the name of the company Mike was talking about now! LOL!That is a service replacement ~750 cfm. carb for a `72 LT1 Camaro or Corvette with a 4 speed. Most refer to them as a 780 cfm, but the straight leg primary boosters on the `71-`72 carbs reduce flow over the earlier carbs with downleg primary boosters. It has the correct metering blocks on it, but someone has swapped out the correct choke components for Chrysler parts. That's not a big deal, the choke hardware can be put back to original, but in order for it to have a functional choke, it'll need to be installed on an intake that has the OEM provisions for a divorced choke, which most modern aftermarket intakes don't have--however it appears the vintage Edelbrock intake it's on now may have provisions for a choke thermostat which means it might be able to work.
These particular carbs also have an odd idle circuit calibration from the factory that would need to be tweaked to run properly on a warmed up engine.
Aside from that, it should work quite nicely up to moderate power levels--but much past 525-550 HP and it'll be pushing its limits, there would be better power in a bigger carb.
That is exactly what I would do in your shoes. That is a really neat vintage hot rod part, and if Mike raises his hand and says he'll make sure it works - trust him.In talking with him, he suggested sending to a company (whose name I can't recall) and have them go through it, then send it directly to him and he would set it up on the new motor.

I believe that intake will work with a divorced choke style carb, but the way Edelbrock designed the adapter plate is a little goofy (why they couldn't just copy the factory design is beyond me) so it'll require a little fabrication to connect--but nothing major. To address the next obvious question--I know many don't mind running a chokeless carb on the street, but for something relatively mild like you're wanting, I would definitely advise running a choke. If you set the carb up rich enough to idle when the engine is cold, it'll be too rich when it warms up.I bet I can remember the name of the company Mike was talking about now! LOL!
I'm just looking to build a muscled up street car and talking to Mike about his 517HP version BBC. Pump gas capable, vacuum booster brakes, not going racing, so do you think it would make sense to bring this carb back to life as it once was, or is it better to just move on? I'll get a pic of the intake for reference below.
