Default 427 IDA 48 Weber Modification Update

Hello All,

I figured since there was so many people that love tuning Webers and was undecided about the 3rd progression hole I would post some feed back.

Well I sent my carbs to PierceManifold to have the 3rd progession hole add to my setup. While the carbs were there, I had them do a look over the entire setup. The only thing that they found wrong was my mixture screws were questionable.

Since then I have installed them with the phoenolic spacers which I made. I took the car out for a drive and what a difference. The transition is perfect!!!!
My current setup is :

60 idle jet
60 holders (3/4 turn out)
40 mm chokes
210 air corrector
165 main jets
bypass 55

I am noticing that the car runs alittle rich at idle but a hell of lot better than before. I am also noticing when at idle and taking off hard the car bogs down but them picks back up. I am planning on changing out the bypass to a 75 or 80 to hope correct this problem.

Now I know what ElJaro was speaking about the true Weber experience.
