Here is a good example of the gain in porting your manifold!
I picked up 4mph on a stock tune!!!
my prior best speed @ the 1/8 mile was 68.89, this run was 69.76.
my prior best speed @ the 1/4 mile was 86.35, this run was 90.40.
3rd and 4th gear pull much harder and higher.
This calculator has been around for years. When the accurate data is used it gives a good ballpark.
