You don't need that much converter with a TR224 in a 5.3, 3200-3400 will cut it, 3400 would probably be best. Don't need that much gear or exhaust either...I haven't read the whole thread, but everything seems matched together except the cam. I like the cam though, if it's a street truck at all the specs are just a hair bigger than I'd like, but hey it's not my truck lol. Keeping the cam as a constant, I'd do a 3400 converter, 4.10-4.30 gears, and single 3" or dual 2.5" exhaust. Just my .02
Thanks, everything is installed already. I can break the stall at 3200 and flash it a 4000k.
Im happy with the out come so far.

Sounds good, I agree that the 4.56's will be steep for your setup. You could always sell them (if you already have them) and step up to some 4.10's or even 4.30's like I mentioned in my post above.
