..it means different thing to different power output.
have a friend that class races and in the 10's. he needs every hundreth of a second from the car and it needs to withstand serious beating.. he has about $5500 onto his 904...
for me i don't need anything like that for a street car that doesn't see the track all that much.. plus my car was only a 12.teen car... 904 was a real basic build.. a friend does them for me.. bolt in sprag, extra clutch in it, alto red clutches, have used different kickdown leavers over the years.. all worked well.. 3.8,4.2 and the 5.0. then one of his home done shift kits.. he doesn't like the kevlar bands so i don't use one.. that trans is well under 1000 dollars and have been very very reliable and should be perfect for a stock 5.7 hemi...
