Hello New guy
Finally going to put my 73 duster back together I took it apart 20 years ago looking for your thoughts from what I remember of the engine from 10 years ago it is a 340 30 over cannot remember compression ratio I believe it was in high 12 has a 590 solid cam B1 heads Crain 1.5 roller rockers Victor 340 intake tti step up headers
Should be just over 500 hp was going to rebuild the 727 with manual valve body Bolt in sprag 3500 stall maybe 4000
8 3/4 rear 742 center Auburn pro differential with 391 gear

I have ditched the front and rear impact bars from back of the
bumpers get rid of the HVAC and went to manual steering what do you guys think of the set up and will I see a low 11s
