318 1/8 time improvement

Ported 318 heads with stock sizes 1.78 intake valves don't flow a whole lot more than a 360 head stock but the higher comp certainly helps not to mention less gear, converter and carb.

A stock 318 head only flows around 170 cfm peak where as a 360 head will flow around 200 cfm. The port volume is significantly higher too with the 360 head
OK you Win !!! the guy has the best and fastest 318 ever !!
