Is this book worth buying?

You also need to address the gauges hook up as well, especially the speedo/tach The stock mechanical speedo won't work with the electrical output from the ECU/trans, so you'll need some kind of converter.

I took the easy route and went with Dakota Digital's VHX gauge set up.

Me too. Just connected the wires and ran the setup on the fuel gauge, tach and speedometer. After that, working gauges. (I had a bad brain box the first go around but Dakota took care of it and second one worked flawlessly).

You'll need an OBDII port to wire in as well.

Does the Dakota gauges have the console gauge setup like the tach and speedo?

Also what transmission mount did you go with for the t56? Prothane looks good. I have the Holley crossmember.

You also have a choice to get the ones set up for console gauges:

Or you can get the all digital stuff. Personally I don't like the looks:

x1. Unless you're dead set on original look.

I say it is, but i'm a bit bias ;)

Just got my LS and will be starting my swap in the next six months. Still doing homework so I'm paying attention to this thread. Keep the info coming.

Guys that are thinking about ordering Holley ls/t56 swap, the one I ordered didn't come with trans mount and you have to use a clamshell mount off a 73 camaro. I ordered mine from Summit or probably go to your local auto parts store and get them.
Motor and Trans are going in Saturday so I'll try and post some pics.
