Cam intake closing importance

At 105 mph, you should be running mid 12s. 3200 is not much stall for a 318 with a .528. As YR asked, did you degree the cam? If'n'itwereme, I would keep the cam, port the heads and add a 4500 converter. I'm assuming you have sticky tires. If so, I bet converter change, bowl blend and possibly ICL change would get you low 12s.

60 ft is soggy. 1.88-1.90 .
If I can create more pumping compression at a lower rpm then the 105 would be my 12.50 ( more torque).
I know small engines don’t make big torque but I do like the challenge of small displacement .
The car is street driven , I’m not sure on the higher stall. Leaving at 3000 rpm with ET streets.
