Value of an LS1?
The problem is, it seems prices for LS1s have gone way way way done in the last year. It is a COMPLETE drop-in engine (PCM, harness, all accessories, all stock components) with 81k miles, and I've upgraded to an LS6 intake with EGR adapter mod. I'm getting told it's worth far less now than what I paid for it BEFORE the intake upgrades.
The best offer I've had so far is $1500, the worst was one guy wanted me to throw in my 21k mile T56 with it for a TOTAL of $1900!

I'm about ready to throw an LS1 intake back on it and sell the LS6 intake separately. If I do, what is a REALISTIC price for this engine?
Also, anyone have an LS1 intake they want to sell cheap?
Thanks for the help,
Adam

LS1's are on the RIGHT track if you ask me! As I said 5 years ago, LS1's are the 5.0 of the next generation.
The LS1 itself that i have has 81k miles
The 4L60E has 18k miles
The T56 has 21k miles
While the engine has clearly got moderate miles on it, the transmissions are quite young!

You also do NOT need to graft the original harness with the LS1 harness - this is one of a few options. You can also have an LS1 wiring harness re-worked withOUT the car's stock harness. You can also buy "Stand-alone" harnesses from John Spear (Speartech, a sponsor of this site), or from Painless.
It really depends upon the emissions you have to meet in your state and how much you want to spend, as to which harness solution is the best. No two swaps are the same.
VATS can be bypassed in tuning, or by reworking the harness, or kept intact with a small electronic "bypass module" (run a search on Ebay for Bakerelectronix), that sends the necessary signal for VATS to the PCM, but can be wired in so as to allow it to be unplugged and put in your pocket, in which case VATS will not allow the engine to start (the same as the original function except using the module instead of the key).
