The load on the lifter is different in a car than a boat ,not !Originally posted by Sydwayz
Cars don't spend time on the rev limiters like boats do, creating the high heat, high friction wear associated with rollers in boats.
I don't know to many vettes or other street cars or boats that stay on the limiters most boat owners are smarter than that --,also the syn protects much better so its what you need in a high heat (which bty is lower than a car ) high friction which in the lifter bores would be the same ,, so syn is still best ,but use what you like thats why there so many types !!
like WHITENUCKLE says above and we all know cup cars and open wheel cars use mobile and red line at 7 to 10k rpms for miles and like he said they use the best and bet they don't ask Teague
what to use
