Re: Questions for the prop gurus

If your motor is truly making the power you told me then a 2.68: 1 should get you just into the sweet spot of the prop. Don't take that the wrong way, remember a dyno can be manipulated to show big numbers but the true test is the prop. I can tell you this from experience that a large boat will pref...

Good job, boat sure looks a lot like a Silver Dollar/Texoma/Red River and the other one. Where did you buy your kit?

Re: Timing chain & Distributor gear on BBC???

You really should set your valve lash on the heel of the cam lobe not at zero. My BBC has a steel gear and it is a roller, I am sure if it is a fully Felber built motor it is right. Unless you are running a crank trigger your timing will bounce a little. Maybe you need to reset the timing, and you h...

Re: welding aluminium fuel cell

Yeah it is the fumes you have to worry about. We put dry ice in the tank and then put tape over the fill hole then poke several holes in it with ice pick that way it purges all the oxygen out and keeps just enough back pressure in the tank so that you don't have to worry about oxygen getting back in...

Re: FAST throttle body efi

The Holley System I can speak for out of experience. I run the Holley HP MPFI on a built 502ci BBC with 160#/hr Bosch Indy Blue EV1 injectors coupled with an 88/106mm Comp Turbo and conservatively in the 1000+ horsepower range. The system is very tuneable, the self learning function is probably the ...

Re: Carb for 454

I'm with Keebo. There are a bunch of math equations that are involved in an engine. Both carbs would work but one is better than the other. I work on my own stuff as well and I always refer to the math and it makes it work at it's optimum when purpose built per application. Call Allen Bills and ask ...

keebo, agreed. Most people don't realize that the stated cfm on a carb is based off of being flowed at 28" Hg so advertised cfm is actually greater than actual flow rate.

Re: Carb for 454

I would like to know why you think a 650 cfm Double Pumper wouldn't cut it? It is real simple to do the math equation and the math don't lie. An engine is just a sum of math equations that equal a specific outcome. A carb shouldn't leak when under no fuel system pressure and engine not running. Afte...

Re: Carb for 454

You shouldn't be getting gas in oil unless your rings are going bad. I wouldn't worry about a marine carb a standard Holley or what ever you choose should be fine. Post a picture of your carb linkage if you can so people can see how it is connected. The linkage adjustment may be way to tight and it ...

Re: Carb for 454

Get your jetting right and it will probably do ok, if you buy a new one I would suggest a 650cfm. More important is the fuel in oil. You need to run a leak down test on all cylinders, it sounds like you may need to do a ring job if you are getting fuel in your oil.

Re: Any drawbacks to having a corp own the boat?

You can actually write off the entire cost of the boat the year you buy it if you have a business. Doesn't have to be a Corporation either, it can be a DBA as well. The amount you can write off in this situation is changing January 1st but if you buy it before the year ends you can deduct the entire...

Jeff, Man I would stay away from any OEM EFI system due to the fact if you need to have any tune adjustments made you have to pay a tuner. If it was me I would go EFI and use the Holley or MSD Atomic and be done with it. I have experience with both of those systems and they are simple setup and self...

Re: Whats the Advantage of having the dual conter rotator?

Just a note on slippage, it is not really an issue with an air prop unless your prop is at a zero degree angle of attack or your velocity is equal to the amount of thrust behind the prop. Thrust decreases as velocity increases. It gets real deep real quick, but I think I would go with horsepower and...

I would stick to what the manufacturer says any more than 3000 and you are asking for trouble. 3200 may be the limit before you have shank breaking issues.

Joe, your statement doesn't make sense. What do you mean your cruise went up and so did your fuel consumption? The simple math behind that statement doesn't calculate. With a larger reduction your cruise rpm's and your fuel consumption decreases. The entire point behind gear reduction is torque mult...

Re: Bbc

If money is not a real big deal why don't you get a larger reduction so you can swing more prop. By doing that you will have a boat that is better on fuel consumption, quieter, lower cruise speed, and not to mention that the torque multiplication would free the motor up and lessen the strain. All th...
