I ran this cam for a couple yrs. it worked great in a heavy car, lot's of low end and up too 7200rpm. Don't know how good it would be in a light car though. I spent close to $800.00 went roller and picked up less than a tenth with a .626 roller. Just keep the springs around 140lbs seat pressure and i agree with sg1586
on the pressure oiled solid lifters.
Zip.
