4 blade warp drive for DD?

I found a 68” 4 blade warp drive for sale in my area for a good price. Just wondering how it would work for my setup or if anyone has ran a similar setup. Setup is a DD stock small block ford 289. Currently I’m running a 70x40 wood prop at about 2700 rpm and im just looking to get the most I can out of this engine for the time being. I’ve heard good things about the warp drives for a DD but just wasn’t sure on the 4 blade setup and the 68” being the right length.

Don't really know how much power it makes, going to assume not much, but I don't think it's enough prop. I would think you're going to need at least a 5 blade in that diameter. Most 160-180hp I know are running 5 blades around those diameters 66"-70".

I had a 4 blade 72” warp drive on my DD 350 with an RV cam as the only upgrade. It was pitched to max out at 3 or 3100. I liked the performance of it and the boat would run dry ground.

Most I had in the water was three adults, extra battery for broken boat and tools for a broken boat. It handled it without issue.

The noise is absolutely terrible though.

O, I was told the warp drives are easier on DD applicTions. Something to do with less torque on the motor.

Warp drive props do not push well at lower rpms, they need to be up on rpms to make thrust, but then they turn on and they perform particularly well at speed, cruise and up. The advantage for DD car motors is that most car motors have very poor torque output at low RPM and they are usually just starting to come in by 2,500 to 3000 rpm. The warp drive does not load the motor at low rpms, letting it spin up quicker to the power band of the motor instead of bogging them down.

They are loud as hell. Choose 4 or 6 blade so you can remove opposing blades if damaged and still get home.
