Default LT1 swap question

Are you modding it? You can disable Vats with a tune.

I wouldn't waste your time/money with one of those. You are probably going to want to remove EGR so you'll have to get a tune anyways. Just have it tuned out when you get a tune. Even if you keep EGR, I recommend getting a basic email tune since LT1's run a little rich from the factory tune.

That will provide the necessary "fuel enable" signal to the PCM. Unless the Corvette also has some other key security feature to engage the starter, that is all you should have to worry about.

Don't you have the old motor that came out of the vette? You could just swap everything over.

Oh ****, lol, I thought this was a vette that was originally equipped with a LT1, I guess I don't know my older vette's that well by looks alone, never checked the year in your sig.

Yeah, I think you'll have to find all the corvette LT1 front accessories.

This might work, I had this bracket at one time, actually owned the prototype red a/c delete bracket shown in the pic:

I'm making my own brackets now because I want a different alternator and power steering pump.

You could sell your factory-style a/c delete bracket and put the money towards that $105 bracket kit. What I'm thinking is that bracket will be a lot cheaper than buying LT1-corvette brackets, corvette accessories, corvette power steering hoses, corvette power steering reservoir, and corvette pulley. You also get a new belt with that bracket which probably is worth $20.
