just a though with the 4V motor, upgrade to the better 97/98 radiator fan, the 96's had an issue with overheating, i got one from a junkyard for $15 and it drops right in

So are you talking about a 97/98 GT radiator or a SVT Cobra? Are the inlet and outlets in the same location?

no, not the radiator, the fan/shroud assembly

GT's and Cobra's used the same ones

be careful with your lack of info. The TSB for the 96 cooling problem had allot more to do than just the fan. The more important thing is the A/c condenser which had the fins way to close to allow enough air to to the radiator.
google TSB 96-25-12

My 96 with the 4V swap would get pretty toasty in the summer, I would regularly hit 238*F with the A/C on. Never had much problem with it though.

Hell, my LT1 firebird's main fan doesn't kick on till 220*F and the secondary fan doesn't kick on till 235.

It took a while to get started. I've been collecting parts such as Cobra exhaust manifolds, a Mark VIII throttle cable, engine stand, etc., but yesterday I got started with the intake manifold removal. This is a much larger job than I had anticipated. I've done many many engine swaps through the years but they've all been on 60s-70s vintage cars. This is a whole different beast. Here is the engine on the stand just as I got started...
