Talked to Holly this morning. They said I should be ok to put in vertical pipe. It is a bit more susceptible to condensation in a vertical position but I'll get a more accurate reading then being 15" away from the manifold. Apparently on the O2 sensor there is a section where it is a little more shielded so I can have that portion pointing up to provide a bit more protection from condensation.
Ordered the Hyperspark distributor. I can run it with my existing coil and the use the coil driver module that came with the system. (if anyone wants to buy my ready to run MSD Distributor with 400 miles on it let me know haha).
So I should be able to control timing shortly and set this thing up for Colorado (not run crazy rich). I will report back after I get this corrected and see how the plugs are looking.
