Hypothetical 318 Builds

1969 318 hone,ring, bearings and second to the smallest purple cam at the time? Been a while. Heads mild Port work. If any gain likely taken away with manifolds. Heads rebuilt with springs to match cam. Street master intake, 4 barrel and windage tray. Mopar performance electric ignition.
On the mild side. Performed well and got 20 mpg on the highway. Good balance between power and efficiency
Perfect. They all don't all have to be 400 horse.
