Yes like Jessel, or any other manufacturer.

I did some searching but I couldn't find the answer. Wondering what the piston dish volume is on the 4.2 motors?

Bit of an update. After about 7 months I was in a position to pull my engine. I had found that water was getting into the engine from the timing cover behind the water pump. I purchased another timing cover and sold the rover in favor of keeping my 3.5 olds. Since the engine has been out I have been able to finish my engine bay, suspension( working on finishing the front brake upgrade) and finishing up on the tranny tunnel. As for the engine I tore it down to inspect after the water in oil incident, ended up going with new bearings but the cam checked fine. Finished my headers and wrapped them as well as a few other things including cosmetics. Hoping to have a drivable car in the next month or two.

Roger,
    Mickey Thompson was involved with the Harvey Aluminum Specials that ran Indianapolis in 1962
with Buick 215 engines - ( Dan Gurney's first Indy 500 - broken transaxle after 92 laps.)  Your front cover may have come from some of his efforts to make the engine competitive in that arena -  He claimed 330 hp on straight alcohol from a 255 cu in version of the Buick 215.

Wondering if anyone can tell me which port is oil out and which one is in in this remote filter adapter?

I figured it out

Looking to put new springs in my olds 215 I am freshening up to replace the current engine. Appears to have factory beehives, I need something that will handle 7000rpm.

If they really are beehives I very much doubt that they are factory items. They hardly existed in the 60's.

Olds were the first with the beehive springs in the 50s I believe. Pic of stock 215 Olds beehive valve spring:

Well live and learn !

Yep, standard equipment in the 215. Nobody quite knew what to make of it.

They also came in 394 Olds, used on 215's for more pressure.

Do 394 springs work with stock retainer?

As I recall- yes. Your results may vary.  Com Cams and Pacalloy have MANY different beehives.

I used a set from Comp Cams around 1990 for my Camaro.  They called them conical valve springs back then.

Conical valve springs are a little different. Not much, but the beehives pull in more at the top where the conicals have a constant slope. Modern beehives also use an elliptical wire cross section.

The objective is to both increase range to allow more lift, and to decrease the spring pressure requirement by reducing the reciprocating mass at the top of the spring and the retainer. I think the reduction in harmonics was an unexpected side benefit. That happens because of the increasing spring rate as the diameter decreases. Because the harmonic is a wave that moves up and down the spring, the increased rate damps it out. Probably the beehive is a little more resistant to harmonics than the conical design. It is claimed that a beehive spring and keeper reduces reciprocating weight (or perhaps it is the required spring pressure) more than titanium valves but I'm not sure if I buy that. However it seems pretty certain that one, the other, or both can significantly reduce the amount of spring needed for a given lift and RPM, thereby increasing cam lobe life and potentially increasing HP output.

Anyone run a crowed 50234 cam? Wondering if I can run it with stock pushrods and rockers?

Possibly.  You will certainly need deeper valve spring pockets & the guides cut down for clearance.

Cam is too big for a 215. It is one size up from what we used in Chris's 300 stroker( 350 ). I used the 50232 years ago in a 215 and it worked well but didn't seem to wake up until over 2000RPM. I think the 50230 would be perfect for the 215 on the street. There is also a 50231 in-between.

I agree with, Jim.  I think even the 50232 is too big for a street 215.  I have one, but it is to go into a 3.9 or slightly larger version of a Rover V8.

The cam I have now is bigger then the 230, close to the 232, I do not think it is even remotely to big for the street. I have a couple of bad lifters and figured I might go for a larger cam.

All depends on what you expect from the engine.  I have a .560 solid lift  cam in my old Camaro.  It gets to be a chore to drive after a while.

I had the CC 268H in my first 215 and liked it a lot. Not sure how that compares to the Crower though.

Jim

Do you remember the specs?

No, they discontinued that grind for the BOPR but it was still available for other engines. It was a bit warm though.
