347 with 44 weber's

I would like anyone with a 347 stroker using 44 IDF weber's to let me know what jets you used, and any settings you use to tune your motor. This would help me at least have a baseline set up.

Greatly appreciated!!

Thank You,

Hi Jim,

Below are the specs on my 347 w/ IDAs.

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

34 to 36 degrees of total timing and the light spring on the MSD distributor for fast advance. I'll give you a call tomorrow.

Timing ok now. I am now checking main gets. What would be the perfect Air Fuel Ratio graph to see on the LM1 between 2000RPM and 3000RPM ?
I tried several jets from 145 down to 130. The 135 stayed between 12.5 and 13 at both rpm's. The 130 jet stayed at 12.5 @ 2000 RPM but jumped to 14 and stayed pretty constant at 3000 RPM. I'm not sure what to look for.

135s look good. 13:1 is a good place to be. Be sure to check wide open too. How's it running now?

I changed exhaust gasket in passenger side today. No popping on that side yet. I am now going to change gasket on drivers side and see. I will try to do a drive test later today or tomorrow. I bought a set of the alumniun exhaust gaskets. I am told they are guaranteed not to leak. They cost $49.00 a set so I hope they don't.
