So... Will it run ok with IDAs? Any thoughts on starting jetting? All these carbs came from VWs so I need some place to start for jetting. I know everyone will be different, but just need a base line. Thanks!

markha - Just keep in mind that the original choke size that Shelby American equipped their 289 cubic inch cars with was 42mm and you can figure the parametric similarities from there. Any ratio of choke area to cylinder displacement below that is going to hurt top end power generation capability, with the flip side that the smaller you go it makes it simpler for the average person to tune for low speed driveability. You have to find the point that you are happy with.
