Heck, I'd prolly stay with a L31 instead of swapping to an L29 if a decent intake was available. I'd buy one on the spot if one was available.

As I see it, the current L31 options are the marine intake or the ramjet350 intake "kit"...which is $1400.
The SuperRam is another option but it (like the TPI) would force you to ditch your AC...or go to the older R4 AC compressor & accessory drive setup. All of these would require redoing the air intake tubing from the air filter to the engine.

Another option, but I fear it would give up waaay too much low end torque...and would not be a total bolt on.
Edelbrock manifold P/N 29135
Edelbrock fuel rails P/N 3631
Edelbrock intake elbow P/N 3849

Total cost thru Summit $510.29 plus shipping. The intake elbow would give a bit more plenum volume but I'm not sure it would help much with low end torque...especially with those short 2.6" cross section runners. I mean, that intake is a super victor for the vortec heads. While it will bolt up just fine that intake is more intended for the 3500-8500 rpm range. With the elbow you would have more room to drill & tap for vacuum lines going to everything. You could put a port on there for the EGR valve. Certainly not a bolt on, but another difficult solution....cheaper than the marine intake but would require some fabrication.
