cam sprocket from an LT4, solid mass sprocket, better design for strength and rpm than standard LT1, also includes LT4 roller chain, better design than standard LT1 buttlink style

$55 + shipping for both

just go to the dealer for the crank gear

 

Is this the stock LT4 or the extreme duty? Have you got a pic?

 

its the stock LT4 set, which is a still a true roller.
Engine had approx 17K miles

I have this same setup (standard LT4 timing sets) in my supercharged and turbocharged cars and have had no problems
