If your gonna do that motor swap, i woudnt even consider running the 98 PCM, swap in the newer PCM you wont regret it!

+1 I just did the 98 to 02 swap on mine took @ 3 hrs, but I extended quite a bit more wires to make it look nicer.

im assuming if it only took 3 hrs you did not do a tank swap or change the gauge cluster.
so did you find a way around the fuel sending unit or are you not getting no fuel tank readings? also did you change out your gauge cluster?

same here. I am having some trouble trying to license it to tune it since it has no serial#. I will be making a cover for the wiring though. just do the swap.

If you are going to "spin it to the moon" I'd suggest a heavilly ported Vic Jr. and 2"+ primaries. I've got a solid roller and was hoping to spin it to 7500 but it made peak power at 6300 with a ported fast and FLP headers
I know it left a lot on the table having peak power that low
