Well I finially got me another engine and trans. I ended up with a 4.8 and a 4l60e. What motor mounts are you guys using for the ls motors and what did you do to for the trans crossmember? I am going to turn the 4.8 into a iron block ls1. I got my pistons in yesterday and the crank is on its way. I am trying to locate some 243 heads and a ls6 intake and a tr226 cam. Also what accessories are you using on your motor (car or truck)? Are you using the truck oil pan? I hope the engine combo will make some good numbers and still give me around 18mpg.
