Quick update:

Committed to the Kelford cams. Had a very disappointing call with WebCams--they sounded dismissive when I said I wanted cams for a 2uz, saying "well, they start at $2700", sounding like they just assumed that would get me off the phone. It did, but less about the price than the stand-off-ishness.

Found a tuner, which was a lot harder than I anticipated. Finally found him by looking up dealers for some of the standalone ECUs. He's never done a truck, but he's a Toyota specialist, and has done a lot of SC400s (1uz) and proved in just a few minutes of discussion that he really knows his stuff and is really excited about working with a machinist on a 4Runner motor. I'm not going to out him until we get down the road.

After some discussion back and forth, I think I'm convinced to go with increasing compression to 10.1:1. This will pretty much cut off the option to do much with boost, but the amount of grunt we'll get out of the motor is what I really want. It's going to mean more machining--smoothing out all the rough edges of the internals to maximize flow, and porting the heads properly. The good news is, with the Kelford shipping delay, we'll have more time to get the machining right.

Starting to worry a little bit about the next weakest link with the added horsepower. The tranny is getting worked, but I haven't done anything yet with the transfer case, shafts, diffs, etc. May just steel myself for some trial by fire close to home.
