The lack of excess oil misting leads me to believe that you do not have a serious mechanical issue. Just a bit of extra blowby to manage.

Here’s my engine at the builder on the dyno. You can see that the output was based on a vacuum pump set up. I’m not going that route (at least now right now) so I’m trying different things.

Notice the oil pressure is always high 60’s to mid 70’s. When warmed up it idles at 60-65. Again, not an expert but trying to relieve the blow from an engine that runs with higher than normal oil pressure. I could be wrong in my thought process but I know I’m not hurting anything and learning my set up better.

Kind of cheating on the HP for that engine with a vacuum pump.

Cheating ? I am stunned at how little people pay attention to crank case gasses.

I see doing the right thing and being rewarded by it.

yeah, expensive system though. At some point I’d like to go to that but that’s also adding to the crank load which hurts power. I could go electric fans and water pump to take load off the crank.

What I mean is using the vacuum pump on the dyno to get the gross HP output knowing that it's very likely the end user is not going to be using a vacuum pump.

That is not correct , the pump alone will give ya 15 hp. And a water pump and electric fans gains are mostly bleed off into the alternator. Which now has to carry the work of the fan and w/p. Making maybe 5hp gain.

But the other benefit is it pulls out all the moisture that condenses inside the motor. Its all upside and no down side. And costs about the same as a set of good elec fans and electric water pump . I think whites kit is 799.00

It is a nice, well thought out, well engineered PCV of very high quality, I like it too.
I'm with you Diehrd, I think people give too little attention to bolwby evacuation and PCV operation as well. The PCV is a controlled vacuum leak (with the Wagner PCV), a tuning tool and good for the oil and engine by evacuating combustion gasses.
The next level is the vacuum pump. 99% of folks are not going to do that, as the gain does not really offset the cost unless you have racing in mind.

First off I'm not Bullish on Skip White engines. Any builder has to figure in profit margins. What you have is definitely fun compared to any stockish type motor! Power is addicting and in a year or so you are going to be figuring out more and more HP. I stopped the dyno run at the end and really looked at the dyno sheet. 477 corrected HP @ 5700 or so rpm using dyno intake stack, electric water pump, vac pump, dyno headers with no mufflers is not real world numbers. Nothing in the paper work claims that the video is the motor delivered to you and it's odd that the video doesn't match the online dyno sheets. Which would tell me that it's a one off motor that they optimized for the video. In all it might be a 420 - 430 actual. It appears that you went with cam choice #2 510/525 lift 230/238 duration.

I think their numbers are inflated and optimized for the benefit of advertising, single plane intake, EFI system, vacuum pump etc. I don't think that means it's a bad engine. Reading all their details it looks like it should be a good engine. Lots of details on how and what they use.

Gkull, what concerns or experience do you have with the Skip white engines? Or is it just that the profit margins seems too slim to be true?

You are correct in the cam choice. And yes, as time goes on I will be looking at ways to add hp. I do know it’s the actual engine from the timing of how everything went down and the carb and intake that I sent them on it.

It's nice that they dialed you before installing the engine. What kind of tranny and rear end do you have?

I have Skip's 434 engine. And had his 427 for 5 years of hard service. I can say factually he uses exactly what he advertises. And if your name is on the build sheet. It's 100% your motor on the dyno.

What most of you may not realize, is he builds and sells thousands of motors every year. Not all assembled and tested , but shipped all over the world for sure. And Skip himself is a good guy who will talk **** right along with ya lol . . . And his prices are in line with blue print and others so he is not alone in offering a fair deal.

Well it pops out still but much less. I’m happy with this set up for now. That breather looks good too. Maybe one day I’ll get the vac pump. Or a 434 swap

I wonder how hard it would be to put another breather hole in that valve cover...just a thought.

I am using the kevco racing kit that has a - 10 hose from the valve covers to a catch can then to the exhaust works very well .

It’s aluminum so not hard I’m sure. Something to think about. Does it matter with valve cover gets the pcv? Maybe I should swap sides?
