Title: I'm buying a new case........what do you suggest?
Post by: airstuff on April 15, 2008, 17:00:46 pm
I am buying a new case for 2276cc  engine over Samba.

What machining options should I include??

Here is my list:


Bore for 94 and deck case.
Full flow and open all oil galley plugs.
Stroker clearence.
Shuffle pin on the centre main.

Other available options-what from that do I really need:???????

Cut for sand seal.
Sleeve lifter bores??
Fill/weld behind 3. cylinder??


It will be a street driven car,occasional strip once/twice a year.

Is this going to be an aluminum or a mag case?

Shuffle pin on the centre main- in my opinion a pointless waste of money (unless it's an aluminum case which already has them so you don't have any other choice)

Cut for sand seal- stock oil return scrolls work just fine, but sand seal works great too.

Sleeve lifter bores- not necessary on an aluminum case, debatable on a mag case (I personally get them sleeved-> peace of mind)

Fill/weld behind 3. cylinder- absolute waste of $$$ all it wil do is warp your nice new case.

Have fun.

Would you mind elaborating on that one. Seems shuffle pinning the center main is pretty much standard these days. Just want to hear why you don't think it is necessary.

Thanks,

If it's standard,then I'll take it :D

And actually,how many of you guys has the lifter bores sleeved in your engines?I am not going to use the agressive camshaft profile,I will use Engle 125 or if I get 1.4 rockers the FK8 but for now Engle 125 is favorite as I have some 1.25:1 rockers.

Brothers does an awesome job on bushing the lifter bores- I've had them do up the lifter bores in silicon bronze and all I can say is those guys don't charge enough (don't tell them that though).

As for shuffle pinning, If you use a quality rotating assembly there shouldn't be any movement of the case halfs.  If there's movement, something is wrong.  If you band-aid a moving center main by shuffle pinning, you will have a broken center main.  Some say extra insurance- I say a waste of money, time, and an unnecessary extra hassle.

With a W125 I would bush the case. That is the reason I had to tear down my 1776 with a W125.

I think you'll find it's damn, as in that's a damn fine cup of tea.  ;)

Seeing tire spelt like that reminds me of a thread I was reading on a predominently US based mail list. A guy was looking for a specific tyre size and someone had suggested a Dunlop tyre to which someone else posted that they had seen some Dunlops and there was no way he trusted a company who's quality control let through products where they couldn't even spell the product right.
:D

how much extra did you pay for sleeving lifter bores?

In my opinion, no.

When I had mine done, Brothers sleeved the lifter bores in silicon bronze for under a hundred bucks.  Last I checked, Rimco was well over two bills for aluminum.
