do u think a k20 would be a better swap??.would it be a much harder swap(even tho it prolly wouldnt matter much cuz i dont think id have enough knowledge to swap it my self id have to take it to a shop)...since a k20 is a newer engine and prolly less miels and more reliable which 400 dollars more. i have 4200 and it says 4000 for the engine but ionno how much shippin and handling usually runs.
