hey again. i have the 305 as said before. i got replies that the LT4 hotcam was "way to much" for a 305. I know the LT4 makes a good daily driver with a radical lift. I also found on the tech pages on this site about how 112 duration cams ( LT4 hotcam is 118) have great engine vaccum and make for great midrange torque with great idle. It also saying a 108 duration has ****ty idle and messe up the computer. the 112 is very similar to the 118 in how it works. If all the info says that the LT4 is a good idling great performing daily driving cam, why is it too much?
