Anyone have a good starting point on Weber 48 IDA's on a 289 HyPo, .030 over, mild cam, std GT 40 Ex. for Venturi,s Emul tubes and jets?

I have a 347 w/ 48 IDAs and ended up here...

38 mm chokes
65 idle
120 holder
160 air correction
145 main
55 bypass
F7 etube

I'd suggest 130 or 135 mains for your 289.
