think you need to read up some..
the factory ecu will need a reflash, as the missing info from speed sensors/trans/gauges/ will send it into fits, = limp home mode..
fuel system.. unless you get a vette or newer lsIII with no return line.. you'll need that+ an intank pump, go price a efi tank..
cooling fans and wire'n
the clutch.. that might eat through your extra 5 bills alone..
the ls engine lack of a mount for the z bar, yes they make one.. thats an extra cost..
bellhousing to mount your m-20/21/22 to the lsx.. sit down when you price that...
I'd stab a 96-02 g.m. truck/van vortec 350 in it 1999.oo(crate, less used) and get 350hp and 17c27hw mpg
the gains you think you will see, won't show up..
your 350 crapy mpg are from the 8 to 1 compression(guesing) and the drivetrain..
my 2002 truck got 28-30 hyway with a vortec 350
they run 9.4 to 1
stock bellhousing will work fine
you'll have to make your own z-bar
you'll have to make a fuel system
any clutch with the right spline count will work
and you can either get a computer programer, or skip the stock route and run MS
Those are costs you need to factor in, but they're not as much as people think.
