Hey, do not get discouraged. I have had the engine out of my boat 4 or 5 times. Getting ready to do it again to work on the transom. I emailed Bob a couple of days ago. He remembered talking to you. Somthing must have made him nervous about your project. He gives the best service and advice I have ever found. Reminds me of the way I do business. Hard to find anymore. If it were my project I would want it set up the way I was going to use it. Not a Drag Car engine in a boat. If you were going to race it every weekend and had a Drive rated for 1000+ HP that would be different. Do you do any of the work yourself? You have the engine out of the boat. I would pull the heads and put them on the "Swap Shop" somone may trade you a set that you need. After that I would get a custom grind to match your setup.

Are you sure that last dyno sheet is for your motor? If you page to the bottom it says it has a 4.030 bore, 3.385 stroke, 5.7 rods and 12.7 to 1 compression ratio. Sounds more like a small block. It is not a 540. Perhaps the data on the bottom of the sheet is not for your engine, but then I would question if the data at the top is.

The dyno operator didn't fill in the engine spec. sheet for that engine, he made a pull on a other engine file, no big deal. But if you are going to give a dyno sheet to a customer, it better be filled out correctly. I would like to see the TEST CONDITIONS, weather/ correction factor.

I looked at the dyno sheet. Is the engine still on the dyno? Whats the deal with the operator? 1st sheet shows peak torque @ 5500, now you show us a sheet @ 4800 peak torque. As I stated before, take the engine up to 6200 load the engine stabilize it load it on nice clean sweep down to 2500 rpms. The test showing 4800 rpms peak torque makes sense. I feel the peak torque rpm isn't going to come down any lower. I just don't understand why the sheet doesn't read below 4800 rpms.

Do you want a new 8-71 BDS polished tall deck, belt, pulley, superchiller? Great deal.

Possibly, I would need to get a new intake or have it machined for a short deck. PM me a price.:sifone:

I don't think that you have that bad of a setup. The cam does not look that bad, and the heads are big but that does not mean they are bad. My best friend is running a 540 with THE 741 cam and Edelbrock heads. His dyno #'s were 630HP @ 5850 and his 24 Baja just breaks low 80's. We can all judge and tell you what we think about the "Dyno" numbers but the only true dyno is in your boat and running it. As I stated earlier lightest and best conditions prop it to 6000. The boat is gonna fly, enjoy it.
I was told when dynoing different cams for the raceboat the cam that made the most power on the dyno was actually slower in the boat, and the cam with the second best #'s ran the fastest. So take the dyno as a referral and when it is in the boat you are still going to have to tune a little more.

If he's not interested in the intake please let me know the price on the intake. water passages on mine need some cleaning up so I might just buy a new one if the price is right.

What I can do is sell you the BDS intake at the same price I would buy a std deck polished from the blower shop and both of you would have what you need andI can move this off my list. I buy at OEM so the deal would be at my cost.
