400hp 318

aa dont worry 318 are just as good as any mopar smallblock!
it just needs the same thing as all the other engines its missing compresion realy good heads intake carb and a good exhaust as built oroiginaly, my old 318 with lightly home ported heads using some of my 2 stroke skills from younger years a good cam some more compresion a set of headers and some other basic things where regulary kicking smallblock chevy but on the street! idled at 600rpm and where pulling hard all the way up to 6800rpm still with smallvalve heads... lots to be done to dose 318´s
its like a 340 it likes to rev high
