So, I have a 455 that I need to build, starting to do the head work now. Im thinking about total cost and what I want from the car. Reliability, I want to daily drive the car. I want my family to enjoy the car with me and they always say they can't stand the exhaust smell in the interior. They dont get it.. haha. So with the engine cost for the stage 1 conversion on the heads, block work, all the parts, fuel injection. I'm looking at a total of about 3-4K. I'm a mechanic, I can go to u pay u pull and grab an LS out of something. So, I want to hear from the guys that have done the LS swap, what LS do you have? Total cost? Difficulty adapting into our cars? Performance? What transmission? Driveshaft? Rear end? Tell me as much as you can so I can make a decision. Thank you guys in advanced. The only thing I do know is, I'm not getting rid of my 455, it will go in one of my future cars!
