Re: My new build for the Ford 408

When your attempting to get a power gain in the straight drive configuration the dollars you need to spend for gain make a gear drive look cheap. I know this because I was there and lived it firsthand. Some things to try: So the addition of the 2 inch carb spacer may add 5-10 pounds of torque. Makin...

Re: My new build for the Ford 408

I have looked at that dyno sheet and am a little puzzled. The engine is making its peak hp up at 4800rpm. My experience from the limited dyno runs Branch pulled were his DD engines would tend to go flat around 3600-3800rpm. That data you posted looks like a perfect paring for a 2:12 gear drive. My e...

Borrow a 72 NGQ or 74 Q prop pitch at the two mark see what you get rpm / thrust wise.

Are they a conical bushing? Round or egg shaped on botton and flat on top with a hole in the center? If they are there are 3 colors (white, blue, black) The white are very hard, blue medium and black softer Most shops stock one or more of the colors.

Re: 350 SQUEAKING

Top area if no interference generally points to ring gap clearance or detonation.

Look for spalling on piston top and I would want to see the rod bearings.

Was the piston that broke on a corner (1,2,7 or 8) of the engine?

Re: 350 SQUEAKING

The piston that broke can you post a few close up pictures of it ? Without seeing it and going off translation it would be hard to find a causation. Cylinders over time will also wear in an egg shape and as the piston travels in the bore they can under combustion forces experience side pressures. Wi...

Knowing Chuck I can envision a radiator capable of holding 5,000psi up on the grass rake built to bust brush as well as cool the engine.

Re: 3 blade vs 4 blade pros and cons

The Levitator 7.4 aka 454 is probably best with a 3 blade JX at that length. The 4 blade will work but with the "advertised" 525hp at 5,600rpm there is not a real need to add the extra blade. I doubt you would be running much pitch with a 4 blade and you note your need is only for a "...

Re: WaterThunder is building the new FORD Godzilla motor

I suspected the cam would be the first component to source.
The heads and valve train you probably can put your own touches upon.
Will any current forged pistons be suitable for a cross? In the Caddy world early on BB Ford pistons had been used with Hemi rods.

Re: WaterThunder is building the new FORD Godzilla motor

Sounds very interesting and that you have a lot going on at the shop. Starting at 475 foot pounds of torque at 4,000 rpm what do you feel is the potential yield for a WT modified version ? Are the new Godzilla engines a totally new push rod engine design or will you be able to draw from existing com...

Re: Gear Boxes

Joel if your going to run a Cadillac 425/472 or 500 on a drive you face limits in using a stock valve train. If bone stock a 1.53 Rotator would give you a gain in usable power and if your careful and don't push the rpm a 1.77 range can work. When you get beyond that you risk breaking the valve train...

Re: Oil Pressure Issue

Are you taking the readings off the same point on the engine ?

With Cadillac pressure will fade from front to back if clearances open up.

If you two gauges are off one T fitting I would be inclined to think one of the gauges may be defective.

Re: Oil Pressure Issue

I can attest that I have had to run up to the parts store before to purchase a oil pressure gauge and plumb it in to verify a reading. Probably for a airboat addict having one in the bin of odd spare parts it’s $25 well spent.
