I'm Awesome
I have a 93 k1500 5.7. I just purchased some vortec heads and I'm in debate on what intake I want to use. If I use the gmpp tbi vortec intake I will have to plumb the egr externally which is easy with stock vortec drivers manifold, but the problem is I don't see any bung for the o2 sensor on it? My other thought was to use eldebroch 71163 and a adapter plate for my TBI. It also has provision for egr, but I'd run into the same problem if I use the vortec exhaust manifold. Can anyone enlighten me on the o2 sensor location for the vortec exhaust manifold? Or my other options for intake/exhaust on vortec heads? Can't find clear answers anywhere
