Dirty- Z lover

I am 15 with limited finance and 3 s130 (79,80,81) i have 1 that has no motor or trans and the other 2 have more than 150k miles or so on the entire car. I have the tools and enough brains to do the engine swap (L28 to any RB series). I have several people that have experience enough to build any type of vehicle bottom to top, side to side. I thought about a V8 swap but ik a few people that have owned 280zx with 350 sbc motors and they complained that it shaked violently. Ik they just "Rednecked it" and just used the motor mount kit and Chevy rearend to do the swap. My grandfather left me the cars when he passed a few years ago. There all bone stock, and i just wanted to know where to start. And after installing the motor what else to do. Please share your personal experience. And please dont be a douchbag. Im just seeking guidance. With only the keys to each car a Chilton manual and what wisdom my pawpaw did teach me. God bless and DRIVE IT LIKE ITS STOLE! -Dirty Powder Springs, Georgia
