DAMN!!!! Done and Installed in a weekend????

OK Don't mean to steal the thread away but one final question and then back to the regularly programmed schedule (thread) wink

So with that said I have come across a 2000 5.9 with 173K mi - locally and guy wants $500 - thoughts?

I would still have to buy motor mounts because I have a Slant 6 in mine

I myself self would go for it.
Sit down and do the math on the extra parts needed to run the low 12’s. I still don’t know the weight of your car but normally this is not a gas friendly endeavor. Weight dependent, is look at the sticky threads on running 12’s & 11’s.
A supercharged engine would seriously reduce the need for a big cam.

Add an overdrive trans for mileage. Aredul gear selection would help a lot. The overdrive ratio for the MP A-500 is (IIRC) .69.
.69 X’s the gear ratio equals the final drive ratio while in OD.

Here is an example;
4.30’s X .69 = 2.96 final drive gear ratio.
A 2.96 gear ratio with what size tire delivers what driving rpm at what speed? (That you drive in.)
Now select a cam that can cruise in that range and see if it fits the ET you seek.
