Well I`m not up to speed on the NOS - cam thing, don`t know what a good cam is for NOS..from what I hear, the wider the L.S., the broader the power band especially for large cube engines, all the builders are using 110-112, I used a 108 first time around and it seemed OK.so I`m shooting for some better #s second time round,,with a 112 and bigger 357 cnc heads and 11 - 1 comp. this time. you have a cam with more duration, which from what I hear will give you a higher power band, which is going to be higher than what you want to use, I maybe wrong though, because the larger the cubes the more cam you can run,,,so, I`m not totally sure what mine is going to do, I guess I`ll have to wait till we strap it to the Dyno and see, but won`t be till after Xmas..I wish I knew exactly which cam would be better, but, I guess no one knows, till you dyno test. because of all the different variables..sorry I`m not being much help,, but thats why I through this Comp. thing on to start with..I do think I`m going in the right direction, with my new combination, I guess we`ll see, in January. Later...
