well I received the 48 IDF's and need a little help with a starting point with the jets. the engine is a 289 stroked to 347 with a hefty cam, 11 1/4 comp ratio, msd. any one out there with the same set-up and their car runs good can give me their settings for a good starting point would be very helpful. My original plan was to go to fuel injection but things have changed so I will settle with webers. I have had 3 other cars with webers so I really dont consider it setteling.

neal, I have IDF's not IDA's, I think that may make a difference, not sure !
just to bring this back up in case someone missed it.went back thru the forum, couldn't find info.
331/48 IDF's
9 1/2 CR
Mild cam
Factory 40 mm Venturis
1.80 Corrector
F2 Tubes
1.50 Main
50 Pump jet
55 Idle
I had 65's Idle jets but they were way too rich, I went down to 55's and all is well. Working with the acc pumps right now.
If anyone wants to try out some 65 idle jets before they buy some, let me know.
Cheers,
