GREAT BUY !!! I love my 97 stang and have done a lot of mods too it !! I have put 373 in mine and the rpm did not change much at all , must say that when I was going to have the 373 put in I was thinking of the rpm's too , but by far out of all the mods I have done the 373 is the best mod. But a shifter is a must too. And I would stay to the 17x8 unless you are setting your stang up for show then the 18's will be nice , I have 17x8 cobra's rims and the ride is nice and look is just right for are year of stang! i will tell you this all so , the mods for this car cost ALOT and seems to be a never ending story but if you love your car like I love mine you will drop the cash!!! Let me know if you have any other questions
