Need Help with tuning Webers

[Eljaro]

the main problem are those 37 chokes. They are sh.t on a 427. 40 or 42 are probably the best.Then you will be able to tune your engine without running it so rich. I ruined my rings with the setup mentioned often on this forum featuring 37mm chokes. Get a set of larger chokes or turn the ones you have to the larger size.
I did a LOT of tuning and trying and almost gave up on the webers, until I put in 40mm chockes. From there I got to this setup:
Main venturi 40mm
Third progression hole drilled
Idel jet 65
Idle screw 1 turn out
Idle holder 100
Main jet 150
Air Corrector 120
Emulsion tube very similar to F14
Pump bypass 00 (would bog down with a .50 when stepping on the gas suddenly).
believe me, the car runs like a champion. Incredible torque and instant response, reving up faster than the tach, so shifting when limiter kicks in at 6500.
And this is still not the end, I am still trying to get it to run even better. The pump bypass will probably have to go back in, but maybe a 20 or a 30( if I can find such a fine drill), because closed I shoots black smoke out of the exhaust when going on the gas.
And I am trying to get a set of 42mm chokes and even will try 45mm chokes, to see how it runs.
Inglese says in its technical primer:
Pull out those small chokes, drop in some large-diameter ones, which may be nothing more than thin-wall "sleeves", and you've got a set of 48 IDA's that will flow enough CFM to make a big block scream.
The 37mm chokes are for SB, for BB you need more air. Believe Inglese and believe me !
