I think your low end power will suffer a bit without a higher stall converter.

According to CompCams CamQuest and DesktopDyno 2003 (take that with a grain of salt), torque is supposed to peak at 2k and hold steady until about 3,500 and then start dropping off. Horsepower is supposed to peak around 4 grand and hold until 6, and that's without a tune factored in.
I've really only driven manuals, so modifying automatics is still something new to me. I'd like to hold off on tranny mods until I get a feel for the new motor. I also tow 4-5,000 lbs around once in a while and don't really want the extra heat a high stall will generate.
With a circle D 3k stall you will get all the performance you will desire and with a tranny cooler you will be fine on temps and tow just great.

Im building a 6.0 for my DD/work pickup. It will have 243 heads, EPS 218/226 cam with 4 degrees advance ground in, and LPP longtubes. I also dropped the coin for a 2600 stall triple disc yank converter for my 4L80E. A converter with a slightly higher stall speed can actually be a benefit when towing.
I hear ya. Quality parts are not cheap. Best of luck with your build. Let us know how everything turns out.
