An aftermarket like PI, AFR, TFS or the PRC proprietary casting can all do it pretty easily with the RIGHT SUPPORTING mods. For everybody who tries it on a OEM casting one makes it and 3-4 fail from what I have seen.....

Something like a TFS milled for the right compression with an upper 230's cam like a VRx5 and a ported fast will do it though.....

No way you will see 450 with TSP 5.3's and a 228. Not even close on a stock bottom. I have seen a couple with valve relief pistons so a big mill would fit and MS4 cam do it but it is not common. Those heads are just not good enough

Mine made 445 with heads about like TSP 5.3 heads and a 232 cam. This is with stock pulley, water pump, and a BBK intake.
With a FAST, pulley, and elec water pump i dont see why a 228R cam cant hit 450.
