The Holley is a great system with many people using it and plenty of support. If you plan on doing a 4L60 or 4L80 trans, you should get the Dominator ECU as it will control the trans as well.

I'm using my 200r4 for now.. I bought the tv cable for the conversion and I have a bunch of money in the transmission as well.
