That particular cam is ground straight up. Peak power was 718 @ 6000 rpm, depends where you want to make your number whether or not you install it @+4*.

741 cams work nice in 509's and merc uses something close in its 525efi,so your making the first 565ci 525hp motor. good job

But hey, I know what you mean by your quote that I have posted above. Thanks for your opinion---I totally agree!!!

Actually, you may be interested to know that these cams actually came from someone you know very well---or perhaps I should say; someone you don't know well enough! Maybe you DO know them and don't care. Anyway, because these cams have had the I.D. numbers ground off, I was was quite curious to know what the duration and lift numbers actually were. Therefore, I took them to a shop called Darren Mayer Performance Engineering in Stevensville, Michigan PH: 269-428-5070 and had them spec'd out on his Cam Doctor which gives a print-out of the all the cam specs of everything a person needs to know about a cam. The cost to spec both cams out was $25 per cam.

You and everyone else reading here should also know that the engines these cams came out of were my own 565cid marine engines that came back from being rebuilt by Jack Bailey of Charlotte, NC. also known as "Budah" on a website what I now refer to as "BoatFraud", but he can always change his screen name. These are the same cams that Jack Bailey told me made 787hp @5700-5800rpm on his dyno---of which I NEVER did recieve any dyno sheets. That's because I don't believe he actually dyno'd them, but only started them up and ran them on the floor or something just to appear that they were dyno'd. These are the cams that Jack Bailey told me were CUSTOM GROUND camshafts based on his extensive knowledge in marine engines having worked at Merc's Lake-X and as a higher management of sorts of the engine assembly at Hendrick's Motorsports. This is the same person who likes to use the "Crane 741" mantra over and over again for several, various engines of differing CID's, etc. He also told me these were a split or dual pattern camshaft----and yet these cams are far from what he speaks of! Sutphen30, this is the same man you are dealing with, and are a Moderator for over at a place I now refer to as "BoatFraud". Being as decent as I can say it Bill, you had better think twice about dealing with those people over there---just thought you ought to know brother.

I appreciate all of the input on my question concerning these cams from all of the rest of you. I am completely aware that cams can, and will vary in size dpending on the application, components used, and the desires/goals of the person having the engines built. As pretty much of the rest of you have explained in your posts, these cams were a laughing joke to expect a cam that size to work properly in a marine engine destined to make peak power at 5700-5800rpm. I ultimately was just trying to prove a point and needed some of your help. Don't fret, I will NOT be using these cams in my 565's. They are for sale for $85 each with Cam Doctor spec sheets for each cam if anyone is interested.

I am a victim of these people Jack Bailey or now known as "Budah" over at what I refer to as "BoatFraud" and I am continuing to expose these guys as these are some of the pitfalls one needs to be aware of and this is just one example of the risk involved when dealing with people who smooth talk you, draw you in with deception and could care less and only want your money. BUYER BE WARE!!!

There is more concerning my experience with these people in the Bad Business column here on OSO.
