18 year old with Mopar project NEED ADVICE!!!

My -2 ) is 2 build the car from the back forward that start with the Dana 60 then a nice Driveline and Driveline Loop and then a nice transmission and then a nice bottom end on your motor and then build the top end of the motor. Or be a teenager like I did when I was your age and start at the top of the motor and find the weakest links.
WELLCOME !
