318 rebuild!

Well i had a 74 duster but needed lot of work so sold it,my d150 is in good shape and is pretty nice truck but hopefully i will get another abody eventually!The cam choice was between 268 and 274 but Ken Hensley made the choice based on the truck but the 274 would not make torque that i was wanting considering it was 318.Was gonna make it a 390 but my funds were limited!What kind of power numbers am I looking at!I also gonna be using mp heavy duty rocker arms!They are also gonna mill the heads so i will have 10.1 comp!
