Board member DirtyLarry did this sway also. I'm not gonna repeat what he though of S&P's swap method. :lol: Unfortunately, there is not much I can recommend S&P for unless one is building an all out show rig.

That's what we need to hear.

What about wiring changes to make the LS engines work with my OBDII diagnostics. Is there a resource to marry them together? OH, I'm not doing an 8.1 in my stepside, no-sireee.
