wikipedia can be innacurate sometimes...
5.3 is an ls based motor. You can swap 241's/243's on to them. Same thing goes for the LQ9 (iron block), you can swap the ls1/6 heads onto it also.
Transmissions too, t56, 4l603, 4l80e etc etc
Thats what I love about these motors, there are so many different combo's you can do to match your budget.
so they do make a alum 5.3 that isnt a pain to make rwd?
i dont know where your reading from but its wrong, what do you think GM trucks come with. They have either the 5.3 or 6.0 motors.
Dont quote me on this but I believe there is like an 80-90 lb diff between the aluminum & iron motors.
so poor teenage messican + iron 5.3 + clean coupe = sponsored dorifto action?
but seriously thanks for the answers fellas. im gonna start looking it all up.
one more thing. it would use the same mount kit and all that as an ls1 correct?
i have a 1uz you can buy.
it also comes with a free lexus ls400
