I have ran both those water pumps. The standard rotation one from the t bird does seem to run a bit warmer but at the same time I added a auto so theres a trans cooler up front which I am sure isnt helping much.
OK it NEEDS atleast 42's and 255 intank 255 inline. It doesnt NEED a regulator but it would be nice. A tune is also needed throw that fmu in the trash. I would expect nothing less then 450 rwhp, should be more though. Put some front tires on the thing too.
They look like crap and weigh about the same as a tank. The challenger came out much better looks wise imo but is also a tank. The the new camaro weighed 3000-3200 lbs it would be sweet, or at least no more then the 98-02 style.
