« on: August 10, 2015, 01:01:00 PM »I think Brent did one, but then you lose the vent (which he smartly added to the tail shaft housing)
Brent to you, correct assessment?
Yup.

Most of my stuff gets Valvoline VR1 non-synthetic 10W-30. This depends on bearing clearances, the application (street, drag race, etc.) and your climate.

Usually when they do that, you can roll the motor over slowly and the lifters will bleed out.

I don't. They get washed and oiled before they go in the bores, but I don't soak.

Where are you located? You wanting a bare block or short block?

« on: July 27, 2015, 09:44:25 AM »
You can scavenge from either place on the bottom end that I mentioned, run through an oil separator, and then through a check valve to the header. We have to do it this way when we restrict the way the crankcase vents to the upper end, like in an application with standpipes in the valley, or an enclosed cam tunnel. It really makes sense too, because you're wanting to directly pull vacuum on the bottom end of the motor....doesn't really matter what the valve covers are seeing.

Are you running a mechanical fuel pump? If not, you can scavenge off the block off plate. You can also pull from the oil pan itself.

BTW,
Here's some flow numbers I have on Keith's Stage 2 Edelbrocks that I have here:
.300 220/162
.400 271/191
.500 304/214
.600 312/231
.700 322/246
This is a 180cc port.

Barry's head flows almost 370 cfm @ .750" lift and at your camshaft's lift, they move about 355 cfm. All of that with just a 196cc port volume. I'm pointing out the port volume because other heads that move that much air usually have a much larger port and much less velocity.
IMO, I think you'd gain a nice little bump with a head change. If I'm not mistaken, Keith's Stage 2 heads move about 315-320 at your camshaft's lift.
Here's the numbers from where I flowed one of Barry's heads....
*4.155" Bore Plate, Intake Flow
.1 102
.2 163
.3 229
.4 294
.5 324
.6 349
.7 364
.8 369

I was replying to the guy with the post in front of mine.....he was asking about the moment of inertia and was thinking it was something related to time. I replied and said it was not a time based unit.

« on: July 23, 2015, 05:59:47 PM »
Contact an engine builder with lots of experience with the engine you're working on. Don't waste your time with the cam "tech lines". Call 5-6 of them and ask if they've ever seen an FE. ;-) You will find that most of the off-the-shelf FE cams are the typical 6° duration split, 110 LSA, 106 ICL. Sure, that can work for a lot of stuff, but there are certain combinations that just need something different.
The guys who can help the most are the ones who screw together FE's every day....and there's a handful of us on here. So ask away.
BTW, most of us are "custom cam grinders" in the sense that we have access to lobe catalogs from the various manufacturers and we hand-pick the lobes based on the needs/wants...then we just have a cam manufacturer grind it and away we go.

"Net power output is going to trump things like frictional losses and moment of inertia losses in terms of the engine's ability to rev quickly."
Bingo.
Some things go against normal intuition and I think that's why most people picture a big ole heavy rotating assembly and associate it with being a slow-accelerating slug. However, if they would just wing the throttle on a big inch, high compression, high horsepower engine once, they would see that sometimes normal intuition is wrong.
Now, as you say Jay, there comes a point where the stroke and piston speed overcome the parts' desires to live happily together....and that point is a limiting factor. However, making the statement that a long stroke engine can't zip up through the rpms is one of those wives' tales that get passed from site to site.

Race T&D, no doubt.
I actually have a lot of confidence/faith in the regular rocker bodies, but once you have pulled a rocker stud out of an aluminum head, you never want to do it again.
