Tweaking the EEPROM TBI 454 is more than a little bit involved. I used one of the original Ostrich flash tuners to refine EEPROM programs before burning them to a chip when I was playing with TPI... Not something I'd look forward to repeating now.
A well loved 454 with flash chips in the PCM will cost you a fair chunk of coin around here. It's almost cheaper to buy a Cummins from the salvage carnies.
You can reach those power numbers with an LQ4 using the GM LQ9 camshaft and tweaking the PCM. No exhaust, pistons, ... needed. You'll get more with an exhaust and other mods but a Cam and tune will put you comfortably in the mid 400's

DynamicEFI make the stock ECU laptop tunable with WB O2 support. A set of stock L29 heads, 214 degree cam, intake and my torque is over 500, and I'm over 450 as low as 2000rpm. 6.0 can't touch that for towing. I have way less into this combination than a LS swap.
