Which to use 1974: 7044212 or 1977: 17057202 on 1972 Chevy Big Block

(1/3) > >>

Hi,
Just got a 17057202 carburetor from a friend.  Was thinking of using this on an Edelbrock 7164 performer RPM intake.  I also have a 7044212 carb with the divorced choke that the 7164 has provisions for.  From what I've read, the 17057202 should be a better performer, but I don't think the hot air choke will work on this manifold.  Can I convert the hot air choke to a divorced choke, or would I be better off converting it to an electric choke? 
Am I correct in my understanding that the 17057202 will perform better, or easier to modify for performance?

Thanks,
Dennis

 Welcome to CHP!

 You would be correct about the 17057202. I would go with that for modifying.

Thanks, but what about the choke question? Can I convert it to a divorced choke or should I convert it to an electric choke

 I would. You can get your E/C kit from Cliff. ;)

The 7202 will provide some easier APT tuning if you knock out the plug and set it up to adjust through the air horn.  I agree with Ethan, the electric choke conversion is the way to go if you want a choke.
