I ran the 041 for awhile in my 455 T400 GTO and then switched to a Ultradyne 223-231-110 lsa-.460-480 lift cam and standard lifters. Nice lope at idle and better low to midrange power. Nice cam but was a little lumpy at idle in gear. With a 4 speed it would be a great cam. Performs close to the Crower 60916 but just a more lopey idle. Lunati still makes this cam.
