will this cam with a 480/490 lift work in a lb9 305 with a holly 600dpvs edelbrock performer rpm manifold,holl blue pump,hollyafpr,bone stock heads thanks for the help.

 

Needs a lot of gear {4.56 best} {4.10 minimum) and a very high stall converter (3500,4000 stall)
needs higher than stock compression 9.5:1 minimum.
Will need a modified very,very aggressive ignition advance curve.
Needs headers and big exhaust.
The carb will need a power valve change.
Needs a valve spring upgrade. #99848 minimum required
Exhaust guide top/seal to retainer clearance may need attention.
stock exhaust rocker arms/stud clearance @ max lift may need attention.

If you don't have that stuff, then its not your best choice.
