I'll see what kind of traction this gets here and possibly post a new topic...

For those of us that have LS swapped our vintage cars- how have you gone back to insure the car?  How did you value the car with the modern suspension and motor and stuff?

See the recurring theme???

Names, Luke. If I hear anyone telling me they're my father....

I have Hagerty with an agreed value. It's definitely a bit lower than what it would cost me to duplicate it, but this is no fault of theirs. I can always raise the coverage. You never get out of these cars what you put into them. I went with an amount I'd see it for should I ever decide to.

I'm currently planning redoing the body winter of 2020. I am going to raise it after that. Just need to find a place to handle the work and go from there.

I've been with Condon and Skelly now for both of my classic's and thankfully haven't had to use the insurance, but they have been easy to deal with so far. Mine is an agreed value policy. I did the same as Updated and used what I currently value the car at as my agreed value. They didn't question the price, but there was a section I had to fill out that gave details on any aftermarket parts I have on the car. I also figured that my build thread would be good documentation of the car if I ever needed to prove anything. I pay $302 per year and they cover up to $40k in damage with $300k in liability and uninsured motorist coverage.

Wow!  It's been nearly a month since any activity on this section of the forum...
For my part, I've put another 450 miles on my TA, largely due to my wife's daily being in the shop for transmission issues.  2009 Avalanche with 188K miles on it, 6L80e trans and it went out all of a sudden.   Those are very expensive tranny's!  While it's been in the shop I've been driving the TA as my daily and that's been a hoot!  Starts up with a turn of the key and idles smoothly, well as smoothly as the cam allows for, runs well in this colder weather we've had and and just works!  I removed all the stickers from it and am going to shoot pictures to send to insurance to get that bumped up.

That's awesome that your out driving it in mid November. We got a mid October cold snap and it brought several inches of snow, so the salt trucks were out here in NY. Cars up for the winter now, but it has me thinking about what I want to do to it this winter. I'm curious, did you ever figure out the issue with having the Holley ECU communicate with the Dakota Digital gauges?

I'm in the process of selling some parts to fundraise and buy a Terminator X kit for my Camaro.

I'm not having any issues between the Holley ECU and Dakota, that seems to be working out alright.  The issue I have is that I still don't have a gas gage.  The harness is connected, and I've picked up the gas gage wire from the dash harness but, it seems that is the wrong one and I haven't made the opportunity to dig back behind the gages and troubleshoot.  I have run it out of gas twice though.  I think early on, when looking at all the wires between the Holley and the Dakota ECU, I was a little worried I wouldn't be able to get it right but the instructions on both are clear.

Are you able to integrate the oil pressure so that the ECU can read it to add a safety such as: If oil pressure drops below x, it will kill the fuel pump? Also, how did you integrate the t56 so that you were able to get the speedo output? And were you able to integrate the reverse lockout?

I split the oil sender and send one side to the Holley and the other to the Dakota.  I haven't gotten into the programming that deeply- great idea tho!  I have my timing set up right now to be reduced greatly if the coolant temp gets above 235.  The factory connector for the T56 VVS is wired directly to the Dakota and there is a calibration sequence the manual explains- you just have to drive one mile and it calibrates the signal.  I haven't tried to integrate the reverse lock out.  I've read people connect to the brakes lights but, I have a very stiff spring to go into reverse so I'm not concerned about it.

Thanks for the tips! Hopefully if I sell all the parts I have kicking around I can buy the Terminator X soon.

Although I haven't seen any info on line indicating this, if you order the Terminator for use with an Automatic transmission you get the dominator ECU and if you order a Terminator for use with a T56, like I did, you get the HP ECU.  Now, in application it doesn't matter if you order the Terminator for use with 4L80E and then connect to a T56, you still get the Dominator ECU, which has more options available.

I'm looking at the Terminator X which is a whole new line of ECU's. They are more budget friendly and are actually different than the HP EFI or Dominator ECU's.
