In In my opinion, upgraded cooling system (I think yours has the old single thermostat setup), intercooler and good free flowing air cleaner. Once the intercooler is on you cam make yourself a boost fooler so you don't throw a code when you turn up the boost some. I'd raise it form the stock 8-psi to 12-14 once intercooler. A better exhaust with downpipe always helps.

With the above it should be comparable towing wise to your 454 but get better gas mileage.
