Good to know the tpi rails would work...I spotted a few pcs of aluminum at work/scrap pile and was thinking bore it, thread the ends and mill pockets for injector seals lol.
I assume with the different heads/valve placement the LS would be a poor candidate for a donor rail.....Guess that leaves the TPI as the only oem that will work..
When this finally pans out, I am coming up with a list of OEM donor parts that work. I want to make this easier for others.....
