hello my name is matthew and i have a 79 datsun longbed i believe the only one in town that i know of but im still in high school got money savin in the bank  but i was wondering if there is and sort of lift i can buy from any where to raise it just a few inches weather it be a body lift or a suspension lift

 

and my bro was wondering if it would be possible to swap out the 4 bangger in there wiht a straight 6 from a z car

Anything is possible...saw an ad reciently for a 510 with a 6 cyl. in it!
any auto supply should be able to hook you up with lift kits...that or try you 4x4 supply shop...
