I haven't posted here in a while...
This past weekend I:
--Replaced cruddy O2 sensor
--installed home-made cowl sorta-CAI. (I'll put some pics up later since that seems to be the norm for this thread)
--replaced the drivers side floor (though, I still have to weld it up. It's only being held in place by self-tapping screws and some waterproofing expanding foam)
--Installed new exhaust manifold. I had one of the usual cracks, almost 360 degrees around the 456 leg of the Y.
I think this coming weekend might be brakes...I've been wrenching for years now, have built three of these things and still I don't like the idea of touching the brakes. I don't like the idea of bleeding the lines without a vacuum.
Anyway, with the new O2 sensor, the CAI, and the new header, I am seeing 15-16 city/highway and 20 or so on a long highway trip; and that much with 4.5" on 32" tires. That's a much better increase from the 9-11 I was seeing the week before!
