i Have a '66 C10 pickup that i want to take the inline 250 out and put in a 350 355hp and 5 speed. i have acess to a 74 chevy pickup that had a 350 in it . i would like to know if i can just unbolt the crossmembers and swap them or if i need to lookinto a different setup? i also am curious if anyone knows of a good 5speed tranny that i could rob out of a latemodel car/truck? :+ 1 4pops}>
