1954 3100, Help me decide between factory frame w/IFS & 4 link or S10 swap

[DENALI]

I am getting ready to start my 54 3100 project and i am really torn between keeping the factory frame and adding a IFS front and 4 link rear to it or doing the S10 frame swap. I plan to bag it either way so either frame will require c-notched in the rear. I plan to use a LS1 engine and automatic transmission out of a 2000 trans am if that makes any difference. I am not concerned about the dollars involved i am just wanting to know the pro/con of going either way and which would be the more straight forward and or easiest to do. Thanks
