They are fair size cams ,It works out to 298 degrees duration with .410" lift , You will need to lift your compression ratio up to around 10.5 to 11 : 1 for these to work properly , A 2TG/3T hybrid with these cams , high compresion , a set of extractors , exhaust and tuned right will push a TA22 into the mid 14 sec mark , So a 2TG with this setup should do low 15's .
