Does anyone know of a site with specifics on the crankshafts used per year? I know it was changed in '99, but how about from 4th to 5th gen? Or Closed to Open block (a1 to a4)?

I have three motors, two '97's and a '99... All three need crankshafts and bottom end work. I found a '94 VTEC crankshaft today for a good price. I know it won't fit the '99, but will it go in the '97 with new main bearings? Thanks, Your help would be appreciated!
