LQ4 or LQ9 swap
I recently saw a Silverado for sale with no engine but it came with a transmission. I feel tempted to buy it and stick a 6.0 into it, and put all the bolts on it as a daily driver. Now I've been searching up on the 6.0 engines and I really want an LQ9 since it has more power but what do you guys think? The roller is a 2003rcsc. Should it be a plug and play situation for the swap? Also would I need to remove a head to see the Pistons or remove the pan to see the inside, so I know what engine I'm buying.

03 LQ9's have full float rods in them... at least the one I have had apart did.. and it's in a friend's truck. Verifiable that old simply because it had the old block with the unequal length head bolts still. Guy still had the Escalade it came from... just was Duramax swapping it. 04 calendar year LQ4's have the full float rods as well which at that point the only difference is the piston... which isn't worth the price difference people instill on them. Plenty of Gen 3 6 liters have the good rods installed.. just seems people are always hawking only ancient junk on these buy sells lol.

I beg to differ my 04 "lq9" out of a caddillac according to vin on the block had dished pistons and pressed rods.... If i had planned on fi on it i would have dug deeper to get a set of floating rods, but unless a miracle happens i will probably kill this engine before i go fi on that truck anyway..... Camaro or yukon may end uo being a different story but they both already have floating rods anyway!!!!
