If you're looking at the Moroso pumps, I think you should give this a look GZ VP104 Super Pro pump seems like a better deal to me, more capacity and less cost. Check it out http://www.gzmotorsports.com/compare.html
Thats what we used on our 640ci. Pretty sure it would be overkill for your engine but it has been a great pump for us!

FWIW we run a Moroso enhanced 4 vane on the orange car. I have it limited to 14lbs and have since the beginning. Tore it down at 223 passes and there was no sign of pin issues. It is back on thier now at the same vac settings. So far so good.
the silver car has a Dailey 5 stage dry sump and according to the data logger sees right at 18" a each pass.

I've had an aerospace pump on my car since 2008. No oiling problems. I have it set to pull about 12". The pump did fail 2 weeks ago at a true street race at rockingham...just put the new one on this past weekend.

Instead of pulling vacuuum from the valve cover you can pull from the fuel pump location as there is a limited amount of oil splashing from this location.
Is or has anyone else tried plumbing their Vacuum this way ?

I have not, but a lot of people do and have no problems.

I do know pulling vacuum from the valley cover is a bad idea. I tried it, it was pulling so much oil the output looked like a fire hose.

I had vacuum leaks that were hard to track down and could only pull 7 inch vac for quite a while on the moroso 3 vane. If I had it to do again, I would go four vain and use a bleed to control vacuum. I don't need one now on my 528, it will only pull 10/12 inches spinning it 50 percent engine speed, or about 3700 rpm. The bigger unit will consistently pull max vacuum from launch, and if you develop a small leak will still give you good vacuum to a point. Plus, for the few extra $$ you are set for a bigger motor if you move up. I use a good, sidebucket oil pan, a baffled valve cover with a large baffle under the breather, set up front on the valve cover. I pull so little oil that I have gone five or six passes and it wasn't worth draining the little puke tank. I also use two breathers on the puke tank, to make sure that if there is any restriction with one, I don't have to worry about it. I wash them once a year.

Is it better? well see in a month or so. Doug
