Ran a set of 97s 330 MPIs from about 950 to almost 1100 with no issues. One ran a little hot with the thermostats so I pulled them and it was fine. May have been time for risers. Fresh water motors at LOTO. Pushed my 330ss to almost 60mph. Very strong. Will probably need shift cables around those hours too.
Highly recommend black motors. 500EFI cam seems mild enough to be similarly long lived.
