Hemi Swapping a perfectly good 70 Duster

I think your fuel table maybe close, but you can see the A/F to confirm before driving if you fire it on jack stands. However, timing needs to backed way down from an LA. My max timing under load above about 5000RPM is 22. It varies based on load. Let me know if you want to discuss before start up.

I knocked 15% fuel out of the whole fuel table since the engine is 15% smaller in displacement. No idea if that has any relevance, but figured it would be a good place to start. For the timing table, I found a few examples online and made some things up based on those tables. It's pretty conservative right now.


I finished checking all the coils and all are correct. Also started messing with the IAC, which in my mind is the biggest PIA out of all the things. I bet I spent more time tuning that thing than the damn fuel tables.
