The last version had 12lb oil rings and ran down the freeway at 3000rpm, only added 2 qts of oil all summer (about 3500mi). This winter it's getting even lighter rings.|

Buy the best oil pan you can afford, to control windage from the bottom up....rotating crank assembly pulling oil out of the pan upwards is more of an issue than what little is coming back down from the top end.
Spend your money on the bottom, on a pan with catch pockets, scrapers, gates and tray..

It is way overkill for the street, but for some people it's just something else to do on their car, the fun is in the tinkering.

|ap72||You could install a cam tunnel instead of stand offs. It can be made to redirect oil around the crank, but has the added benefit of keeping your cam and lifter submerged in oil.|

|Richiehd||Im a middle of the road guy! I use four standoffs on one side only, the passenger (right) side to prevent oil from blowing back up into the valley and help with windage. (just my 2 cents)|

|Biscayne327||I had plugs in my 327 block and the cam after 12 years was fine , I should think that there is enuff splash from the crank so you really don't need those holes.|

I'd just love to see 6 dyno pulls in a row with the motor running at max hp for say 5 minutes on a mule motor without these then 6 more pulls with them all other conditions being the same. This would give a good average and take into account the dyno tolerances and allow the oil to flow. I'd bet there wouldn't be much if any difference.
I wish I'd thought of the items. Could probably finance another project. haha

|sexypizzaman||well put bogie, I will forget it then, besides, wouldn't you rather be on the safe side having more getting to the cam than not enough?|

While I think that if you just gotta try out your tap and die set, the stand offs are a better solution than plugs, as they at least provide a path for blow by that isn't sharing the same holes as oil drain-back on the ends of the block. But in the bigger picture I have to wonder if all this gnashing of teeth over those quarter inch holes is worth it to anyone but the purveyors of tap and dies sets, stand off vents, or hole plugs.

|4 Jaw Chuck||Meh, save your money. Not a mod you need to make for any street car and a questionable one for an all out race car at that.|

|DoubleVision||Unless your on a race track trying to win money and trying to squeeze every last horsepower out of the engine as possible I`d say these are a good idea. If it`s just a street machine I`d say don`t waste your time.|

Lifter valley standpipes?
Hey guys take a look at these.
I read an article in a performance SBC book I have writen by David Vizard that says these are a great addition to add to your block on assembly if NOT using a flat tappet cam. I haven't heard or seen these used before but I guess they limit the amount of oil that drips through those 8 lifter valley oiler holes to reduce windage? I plan on using a roller cam for my 383 build so I am considering adding these or even just brass 1/4 double ended pipe from the local hardware store. Is there any significant benefit from these things and what else can you tell me about their purpose?
