Carburetor Question - Is this a good call?

It may need jetted down.
Again watch some holley viedeos, also you bower valve may be bad in the carb.
If the timing is set to factory specs, it may need more initial like 12 BTC.

I'll check my timing and see where i set it and report back. I was THINKING about jetting actually.. but with my exp level.. not sure what i can do there.

I had a 1406 on my 66 formula S with the 273 commando and it was great. No problems there.

If you can find the original 500 cfm avs that would be a good match for the motor too.

Good luck

I've been looking for that carter everywhere.. but they dont have electric chokes and i'd like that feature.. but good to know it worked well
