I'm totally confused now, I thought the drivers weight was added to the shipping weight? The shipping weight was divided by the HP

Rich said his car weighed 3418. One would assume that's with the driver weight added. So, the 170 needs to be removed to find the natural factor for the car. Then you would adjust to the lightest possible weight for that class. Then add the the driver weight for the total weight with the 2 bbl .combo.

I’m still wrapping my head around the 350cfm for the 305 2bbl and 500cfm for the 350 2bbl.

302 is 287cfm and 351 is 356cfm. Only wish Ford had 350cfm on the 302.

305 uses "medium sized" 2bbl, about 325 CFM.
69-70 350s use "really big" 2bbl, about 400 CFM.
All other 350s use "big" 2bbl at about 350 CFM.

FFFFord put 350 CFM carb on 82 manual trans Mustang GTs only.
