any 225 performance ideas

i agree im not ready to try a turbo :???:.... and i never said i cant do an engine swap... i have just only replaced motors with the same motor... that's easy... what i dont know id if i put say a 360 in do i need the k frame or are conversion mounts ok.... should i replace the shocks and springs or are the ones from the six enough sense its a kinda heavy motor .... and were a can find a new drive shaft because i assume it will need to be shorter....those types of things are my concerns.

they weight almost the same
