I have found a LY6 out of a 2008 sierra 3500 should I get the wiring harness and ECM I don't need any smog equipment I will be putting it in a 1963 Nova I plan on getting a LS3 intake and changing the cam will this ECM be able to be programed or should I look for a harness out of a F body car?

You would have to get the harness from a 2010 or newer camaro.

If you get the harness remember that you are stuck to the way it is routed. That harness and ecm will work for your application. You will need to extend the MAP connector.

If it won't cost extra then you might as well. Having extra wiring and connectors on hand couldn't hurt. Never know what you might down the line.

The guy wanted 200 for the ecm and harness

Could resell the harness + ECM for that price or more.

My vote is fork over the $200

Offer $150 first.

Take every piece of harness,connector,tube,fitting,bracket,fastener that they will give you for the cash that you bring,it is always cheaper and easier to sell off,trade or scrap what you don't need than chasing after it later.

yes , well worth the 200 , the e38 is program-able

My advice ditch the VVT that means the harness and ECM. 200 for that ? ha

If you're putting in a Nova. All those wires is going to look very bad.

You can purchase a VVT - Delete kit for cheap. Find a LS3 intake for super cheap. Get a harness anywhere for less than 375.00 And ECM's are nickels meaning they are everywhere.

Do this and you could be pushing 500hp maybe 550hp with the right cam.

Just my advice..... I don't think you'd be happy with the look of a LY6 with all those wires... in the long run. Better to get it over with now.

I am keeping the VVT on my L92. As said above I would get it and everything else you can grab.

And here it is I got the harness and ECM he gave me the harness for 150 and the ECM for 50 so not to bad
