since a crane 741 is not available what about a teague stage 2? anybody run one of these in a 509?
TCM Camshaft: STAGE 2, MARK IV & GEN V, HYDRAULIC ROLLER
Operating Range: 3000-6500 RPM
Duration Advertised: 296° Intake / 304° Exhaust
Duration @ .050'' Lift: 234° Intake / 242° Exhaust
Gross Valve Lift: .610 Intake / .632 Exhaust
Lobe Separation Angle: 112°

looks identical except for slightly less duration

That looks like crane's 139021.

Call Bob at Marine Kinetics. He will make you a cam for your specific motor combo and it will run incredible !!

He specializes in custom cams.

Call Bob, he will custom grind to your specs. Tell him what you have and what you want to do with it.

For the price of that teague you can get a custom from Bob at Marine Kinetics
I was just going through the same debate, I was trying to find a 731 cam,
but after to speaking to Bob on the phone and listening to all the recommendations from guys on here I decided to go with a custom one from Bob,
give him a call
he will tell you all the info he needs, and be honest about what your doing with the motor, and he will set you up
his price is literally only about $20-$30 more than those teague cams

I highly recommend Bob as well. He definitely makes power and really knows the Marine industry inside and out!!!

You might be able to get the cam thru Scorpion, they purchased Crane... Teague might be getting it thru them as well caus that's where he's getting his roller rockers with the name etched on it.

you can still get the 139021 at jegs. if i recall the the 139021 is for the mark 4's and the 168741 is for the later engines. you may want to check for sure on your application.

Glad to see you too my advise. A lot better dealing with Bob than others I have delt with.

I called bob earlier today thanks for the advice, mike
