Today, dollar for dollar, is the 318 faster than the 340 ???
1) machining of blocks more accurate
2) roller cam provision without retro-fit costs
3) cylinder bores hardly wear, due to efi
4) better piston and ring package
5) literally hundreds available in salvage yards
They are THE perfect platform for the budget builder, most of them can be refreshed with a ball hone and a bearing job, its difficult to find many LA 318s that dont need machine work anymore
