Re: Prop reference point

I have no way knowing how your front mounts are constructed, but it may be easier to add a washer under the front mount(s)? For practical purposes, that may be an easier method to attain the same desired end. I've done this a couple times in the past, and it works just as well if all the other param...

Sliding Gator is spot on. Sounds like it may be a little high in the back. The second post in this thread expands on motor trim adjustments. According to Hoyle, would be a straight & true bottom with no hooks, rockers or dents. https://southernairboat.com/phpBB3/viewtopic.php?f=85&t=28600&am...

1 If your old 2 barrel off your 220 is a 500 Holley and has not been re-tuned for your current engine, that is a much larger part of your problem than you realize. . . unless it was running pig rich on your ground power, it is not supplying enough fuel for you to exercise an early 500 Caddy. . .

Re: ISO Sensenich Q to try out

If wiping it with a solvent doesn't expose the number(s), you may need to use an old toothbrush (or something similar). Sometimes the stamping of the numbers is fainter than it should be. With the carb installed where you can't turn it, a flashlight may in fact help ascertain what they are. Rest ass...

Not unusual for the thickness being discussed. No reason to think it isn't UHMW. I have 3/8 on mine, and I agree with your observation. I don't see it being a willing participant either.

Re: ISO Sensenich Q to try out

If you have some carb cleaner or acetone on a rag, wiping the face there by the air horn (marked yellow areas) should easily reveal the list number you want. It is stamped there, so it's generally not necessary to remove all of that soot (although that wouldn't hurt anything either). https://souther...

First of all, I will say that I'm in total 100% agreement with the assessment that you will not beat a properly built Quadrajet for a 500 DD when and if you have one one hand. Unfortunately, they are not as plentiful as they once were. They baffle people who don't know how to tune them, who have sub...

Tim, I don't know that it would make any difference in your specific case, but my situation is a very similar to yours.

Re: Airboat for floundering POC

No such thing as a 502 Caddy, never was. I thought that fabricated rumor had finally died in the early '90s.
Obviously the seller knows little about the engine. I would hold anything he told me suspect, at least pending verification.

Re: oil consumption

While it may not seem likely, there is the possibility that you unknowingly overfilled it. If so, it would likely expel the excess to a level where it is happy, at which point that expelled volume would subside dramatically. This is something you need watch carefully because if it does not (subside)...

Well, there you have your answer depending on whether you were after fiberglass or aluminum.

In any case, the later of the two was nearly a foot wider than the other, and would be my recomme...

Re: Gitsu 0520 Crankcase venting.

I would have to agree with your buddy. The intrinsic problem with the venting hose(s) being at or near vertical, is that when you inevitably get condensation inside them, it has no other option than to run back down into the crankcase. Ideally, although not always possible, a little down hill run wo...

Re: Intake installed backwards

The stock intake works very well for a DD. It will work even better with a 1" spacer, as it is lacking plenum volume. That is what I've run on mine for years, and debatably works as well as the 2115. It's definitely heavier though. Given the ROI for 2115 upgrades with a DD, I opt to spend that ...
