Or, if you make a wrong turn at the Daytona Dog track, or just make a bet in the parking lot after having a few too many beers...

"I bet my station wagon can beat your corvette, 200 laps on the road course, lets go!"

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.

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)

F-BIRD'88 Funny how none of the OEM factory race efforts neither used or promoted any of this eye wash.

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?

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?

Thanks,

Has anybody ever wondered why Small Block Chevy guys worry those little drain holes along the main galley to death. OMG, these little holes are going to cause crank windage that results with insufferable horsepower losses. Has any body looked at the holes over the cam in a BBC, BBF, or a Chrysler? They don't seem to be very concerned about those big to really big holes resulting in enough oil drain-back to reduce power output.

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.
