Finally got this thing dynoed. 337/334 with an ignition issue, bad plug or wire, not sure. Would have changed them out, but they didn't have the parts at the dyno shop and we were time limited.

Just thought I'd report back. Did some dyno tuning on the L33. Probably made 20 pulls, no oil leaks. Looks like pushrods fixed the problem. With .581 220/224 112+2 cam it made 337whp and 334 tq with...

I have carb, so I think it is a vacuum leak as it will be going to the manifold.

Pretty happy about a good leakdown test result. So now I just need to decide on a system for getting suck to the crankcase.

-8 no good? I happen to have a bunch of spare -8 fittings.

And what would you do with them? The fittings on the valley cover and the valve covers are all 3/8.

OK, got my catch can. Not sure that I'm all that impressed. It's pretty simple, one inlet one outlet, 3/8 NPT with a little dipstick on top.

If I use this, the idea would be to T the lines...

It's a trailered autoxer and I have about 15 minutes behind the wheel so far, so I can't tell you how it would affect things on the road. I can guarantee that it would take some getting used to, but...

Somehow I missed that comment before. I'm glad you quoted it.

Not much to see right now, it's got the valve covers plugged and a 3/8" hose from valley cover to the carby intake manifold. That's...

Didn't think I'd get it out again this year, but my LS6 valley cover showed up and there was one more autox, so I got it out there. I was unsure if the valve covers were baffled, so I just plugged...

I think I just stated the example badly. I was saying if you revved up the motor to 80 psi and then closed the valve, you'd have 80 in the sump (65 + 15).

That's exactly how I had envisioned it.

EDIT--Interesting on the rev to fill idea. Wouldn't that likely be the same as closing the accusump at idle pressure then adding .5 or 1 qt?

I had always thought it worked slightly differently: if you rev up your engine and close the valve, you'll trap whatever pressure the oil pump is producing in the Accusump. So it might have 80 psi in...
