1970 Dodge Dart 318 upgrades
So I am going to back peddle since I never really looked at the cam without some of the other changes I have made. That is the same cam that is going in the Duster so I was interested..... Again this is a model but it is telling. The cam will make the biggest difference for low end torque outside of a stroker (did not include that data). All other items effect 3000 and up..
Next I looked at the difference between Stock/Stock with the Cam/My 318 build for the Duster. Notice in "cruise" RPM the extra $2500 I have in mine did almost nothing to where your stock with a cam is.
Then I added the 4 Barrel..... Unclear if it is worth the trouble if this is a cruiser but remember this is with a stock restrictive exhaust/small valves so the top end likely has more than these plots show if you let it breath better. The carb in itself would not be much help.
