so I am new to the world of K5s as I recently got an 88K. It runs and drives pretty good with a 350 our of an early 90s model pickup and a 3 speed trans that is kinda a mystery. I would like to do a block up 350 TBI build, nothing crazy just something durable with a little cam to it. The truck was original an automatic drive but the previous owner did the transmission swap. I would also like to build a new transmission for it preferably a 4 speed. I need help with suggestions on good blocks to start with, decent heads, cam, and what trans to pair with it. I would like to build the motor and trans and just slide it on in place of the ones in there.
