Might need bigger axels per say, as that 5.3 in your 1500 produces more HP/torque than a BB 454 did when that K20 was produced. Hence also why the 8 lug 25/35 series trucks have 11-12" FF axles vs a 10.5FF or 9.5" SF that is on my two 2500 GM pickups with a 292 I6 in the 81, and a vortec 350 in the 2000.

That truck was originally a carbed 350. I recall those and they were NOT impressive!
It has a Stock Vortec 454 with an Edelbroke carb, headers and a traditional HEI in it. And it does ok with the 4.10s and big tires. Wouldn’t want to pull much if it had a 350 and tall gears though.
