Recently built a lq4 with 243 heads, sloppy stage 2 cam. long tube headers (1 7/8 to 3") and ll 3"' duals out the back. block up is gen4 5.3L parts, i changed reluctor ring and cam gear to be used in the 08 silverado. the 08 has 160k on it. trans shifts and performs great , but i need it to last a while untill i can afford a lvl4 or built trans to handle the 6l. i left all the factory tqmgmnt on but used bluecat tool to adjust tables. i know i have to be easy with the skinny peddle obviously. i also have a 40k cooler im about to put in , just got truck going a few days ago. i dont need a straight pooch but as good as i can get to try and make this trans last.
