the 284-484 wont make enough vacuum for power brakes. Its 248* @.050" and ground on a tight 108 lsa.



There are (2) 284-484 cams..

The older version #P4120231 has significantly more overlap (68) and delivers less vacuum..

The later version #P5007696 has an overlap of 56 and delivers higher vacuum along with better driveability..

Don't use the #P4120231 if you have power brakes..

Just my $0.02..
