I don't see where people see extra money, If you were to do a 10's 340/360/408/416 it probably trick flow solid roller single plane 850 cr good crank and rods what would a 318 need that's all that different? It's only 7% smaller than a 340 so it would only need to spin that much maybe 10% to makeup for the airflow loss by the bore.
It’s not as much air flow as you think it is though it is there as an issue, it’s just a lot smaller of an issue than you think it is. It’s really displacement. Or lack there off.
I double dog dare you!
Or at least beat me to the punch.
What you described is what I want to do for the challenge & chits and giggles for Austin Griggs 318 fest. No other reasons
I have a ‘67 - 318 engine, W2 heads and 3 different intakes for it. Currently working on the racing Duster.
