Best improvement for handling before you tear into the IRS is to add full length subframe connectors.
What is the purpose or intent of the improvements? Tightening up street driving, autocross, weekend track car, quarter mile car?

I ran out of pump at 450 using a DW300 which is supposed to be 340lph. I would not expect a 260 ish pump to carry 450hp.
You using the same injectors? Duty cycle would be irrelevant if not on the same size injectors.
Please tell me that was an attempt at a joke…. It’s a sales display. Private stalls there. The public toilets even have a music feature to cover up any additional noises……
You have all the front accessories from the 03 motor? Alt and bracket, water pump, pulley bridge etc?
you could run the same tank but if you leave a stock 01 pump in it expect the motor to last about 4 seconds under full throttle. If you have the 03 fuel hat with dual pumps you have to tear...

The factory boss 302 rods were a common upgrade when they were cheap from ford. Ford caught on and raised the price so most go aftermarket now. They are supposed to be good to 600 hp iirc.
Have a procharger now on mine. Fun as the revs go up and tuned safely. No torque hit down low so a little easier on internals iirc. But after this I have a forged long block and an Eaton swap sitting in the garage for when I have time to get it all done. If you want 425-450 a used...
NOS is New Old Stock. A new part that has been typically discontinued by the manufacturer but is still new in box. Differentiates between new and available and new but unavailable. Muscle car parts that were NOS were a big thing on a correct restoration. Usually meant the date codes were...
With a 4K budget you are looking at a used procharger kit and tune. Stay at 400-425 and the motor under 3k will be no more stressed than it would have been NA. If you don’t drag race and it’s a weekend cruiser with conservative timing the motor will be fine. Compression and leak down test...
