My dilemma. Need everyones input! I currently own a 2001 camaro SS with pretty much full bolts on. I have two choices to make in regards to the motor. I can either pull the LS1 out and sell it for a good price and drop in an LS7 or Cam the LS1 and feed it the bottle. My dad works at a GM dealership so he can get the LS7 at cost. I just dont know what route to go and would like some peoples opinions on it. How reliable is a nitrous set up? how hard will it be on the motor? etc. If anyone has any pics of the 427 in their camaros please post them. i would love too see! thanks!
I would agree with the last reply in that the LS1 and the LS7 are the same outside physical dimensions and basically the same weight with an obvious advantage in torque and hp . Nitrous damaging an engine will happen over time if used somewhat sparingly and if used alot will damage fairly quickly . Just be careful with the LS7 as it could be easy to get in trouble with the law or worse , sorry not tryin to be You're Dad just keep everyone safe . Good luck
There is no way nitrous is more reliable than the ls7. You will need to extend a few connecters and such with the swap but you will have power on demand all the time instead of just when the juice hits. Either way the trans and rearend are going to eventually need upgraded.

But remember, if you go with the ls7 and cam it, you will want yo go with a larger cam than you would in an ls1 because your power will come in sooner in the lower rpm range...I had a 238/242 that was pesky and bitchy on my 346, but when I went with my 408 I pulled the cam out and put it in the stroker and it acted like a baby 224 in a stock cube motor
It's a good read. For engine swap, refers to "Engine Change"

exactly 
None of the above.. If you're going to spend big money on a new engine, get a sleeved, forged LS2 427 CI with some LS3 or LS7 heads (TSP 6 bolt 265cc LS7 $1950/pair assembled). You can get the 24x reluctor so you won't need to run a conversion box or tear into a LS7 crate motor. I have an LS7 in the garage, and the whole oiling system is a pain to swap over, as well. Buy a nice longblock 408 or 427 for half the price of the LS7, twice as strong, and have a sturdier engine with the correct oiling system, correct reluctor, all you'll have to modify is your knock harness.
