That is a very small cam and will definately limit performance and top speed  :thumbdown:

The problem with America is stupidity. I'm not saying there should be a capital punishment for stupidity, but why don't we just take the safety labels off of everything and let the problem solve itself?

86 that cam...and if you don't ....make sure spring seat pressure will work along with the rest of your valve train...just my thoughts.

That camshaft is what I would call an "RV" camshaft...It will make respectable torque at the bottom end (not required on a jet pump) and will "fizzle out" at the top...Almost the exact opposite of what is required. :thumbdown:

Perfect cam for the tow vehicle though... :thumbup:

Hydraulic is fine unless balls out engine. that cam will run in the 5000-5500 range, however it is possible to turn, remember torque and HP meet at 5250 RPM. the cam will depending on its specs can make more hp .
