Hello everyone from the site. I am a new member to the LS1 site but I've been lurking around the forums for a while now. I am a proud owner of a stock 99 Silverado and a 69 Chevelle that is now under construction. My main focus is to get my Chevelle up and running and do a complete pro touring restoration. The body work has been done as well as suspension. I was going to use a SBC 350 with a 700R but as of last week I came up on an 5.3 vortec from a 2005 tahoe with 65000 miles for $700 that I could'nt pass. All wiring, ecm and accessories are there and this is why I have decided to join this site. I thank you guys in advance for any advise and guidence in my future project and hope to be pointed in the right direction.
