That's a shame mike . The last thread I started is when you stopped. I'd say from what I've seen you are more than qualified. I went with the one you recommended. It was 1 number off what was suggested by the other guy so I'd say you know pretty damn good!!, who cares what the other one or two have said they probably don't even have a boat if u know what I mean. If we don't learn something everyday then we waste our time . There are tons on here that know it all and have never built a thing. I'm building my first engine and have drag raced for 20 years and it's people on here that help me through it and I'm scared ****less cuz I want it right

I think it's funny that people get worked up over all the cam threads. Bob get's recommended on almost every one because that's what he does for a living, and has a great reputation. Mike, I think your Crane 651 recommendation on Shane's thread was a good call, it is a tried and true cam that performs well in that size engine with a power adder. However, there could be better options, or there might be a parameter or component of his build that would benefit from a different/specific profile. I'm pretty sure if you did call Bob, and the 651 profile was the best option for your application, he would say so. Just because two cams have very similar numbers, does not mean they are the same. Overall lobe profiles can be vastly different between the two.
So let's turn this thread around.. If you want to get any meaningful responses on a cam thread, and I'm sure Bob would chime in if it's constructive, you need to post as much detail as possible. Asking what cam for a 540, is like saying how long is a rope. Johnnyboat, seeing as though this is your thread - You've got 557's, 10.5 comp. What heads, any porting, what intake, what size carb, efi, what exhaust, straight out, 90's, mufflers, what octane fuel, what is the application, what springs, rockers, pushrod size, what cam is in there now, where'd it make peak torque and peak hp, was it dyno'd with your marine exhaust, or dyno headers? Answer as much as you can and that should be a good start. There will likely be people who aren't cam experts, but may have a similar combo and can give you their real world results with what they're running, that way everybody should be able to learn a little something.. Or if that's too much work, just call Bob
