Yep, and diapers under the oil pan------------

Also they have just started something on a new improved retainer system for funny car bodies--they been blowing a few off pretty high and far (think spectator safety)

Going to the NHRA races at Route 66 next week end----starting line credentials, and If Cruz can win it-------------

Fresh block arrived today from Shaun (rockit) Shaun had a nice clean spare block and kindly let me have it to keep my project on track, Cheers Shaun your one of the best

Heres a pic of the original crack in the first block.








Had a good look around with a magnifying glass and everything was good to go, started off by pulling all the oil gallery plugs out and drilling and tapping for 3/8" NPT pipe plugs.













I need to go round and remove all the casting flash off for better oil return but first need to get the block onto the mill to deck the block and dowel the main caps and do some other bits and bobs.








While ive been awaiting the block to arrive i've been busy building up the baffled oil pan, Its a stock pan cut about and fitted with baffles and swinging oil restraint doors.
I started with a stock pan I had beaten straight but couldn't get it smooth so considered it sacrificial to the cause It now holds a lot more oil than a stock pan and keeps it at the pickup where it belongs















Here the main removable baffle is back in position. 2nd pic is with the modified pickup in place.








Just need to paint it now.

Looking good on the pan! About that crack - I for one was not following that it was a longitudinal crack along the bottom edge, but thought it was a vertical crack only ~1" long. It will be interesting to see what Pat says about the possibility of repairing that long crack.

Never seen a crack go vertical Roger, they always go longways when its frost damage, The old block is gonna get repaired by welding with Nickel rod and kept as a spare.

I don't understand why you want to dowel the main caps----------they should be fitted properly in the register and even as good work that you do you will be interducing 20 points fo a misfit----------

Didn't know you could repair a cracked block? Does the Nickel penetrate the crack better? I had heard someone say you can't weld cast iron? Then again I know next to nothing about welding, thus your threads are a wealth of knowledge for me!

Marty at MTS Cadillac suggested doweling the caps as my motor is blown. Caddys are only 2 bolt main. Not quite sure what you mean when you say misfit 20 points

Anything can be welded with the right gear Steve, I've always arc welded it with nickel rod.

Wish I knew that before I tossed an old cast iron frying pan with a crack down the middle. That old pan was so well seasoned we used it with the crack for years, until oil seeped through it while we were cooking, and it became a fire hazard!

Heres what I mean---you have 10 bolts----a dowel has to be in the cap and in the block--10X2 =20

When a block is made the caps are fitted to the register with an interferance fit for locating(sorta like dowelling?) then the block is align bored----------any effort to do any mod to that setup will require another align bore/hone to correct the bore to the possible relocating of the centerline by the mod.

As good as I am with doing things like that, the odds of some of those 20 places being exact grows beyond what is reasonable (and I do lots of main cap replacement,etc)

Furthermore, the main webs on that engine are sorta skinny and some extra stress around any fastener will be a source for a possible fracture up to the cam tunnel----a very slight outward force will almost guarantee a break up the oil passage to the main

Not trying to be an alarmist, or to cry WOLF, but in my opinion its something you don't want to do----------

there is photos of blocks with busted off lifter bores with holes below were a sleeve would not fixed it were i welded them up . photos in my gallery i have put in oil pan rails in many dart big m blocks as sleeve all 8 holes.re lined oiling galleys of blocks were rods busted threw a oil galley or were bored threw with a boring bar (bone heads) not to many thing i have not fixed on a iron block doing two bbc 10.200 blocks were they needed sleeves .one was cracked at the lower part of bore then up and out on to the deck threw a head bolt hole and over to the outside of the block. both fixed

yep jerry i think i good to. no way in hell would i bet on pinning the mains with out a line bore or hone. not bumping one off on the 3:00 to 9:00 you would be very luckly

After the main caps are doweled it's going to be align honed Jerry, maybe I should of said this earlier, it will also be getting a girdle.

.

the 472/500 Caddies with a main bore that is huge at 3.4383-3.4390 which doesn't leave much material between the main bore and the cam bore for strenght, has real skinny wings out to the outer walls and puts 2 vertical oil passages for a place for the main to split out---It is not an engine I would use/recommend for big horse power---

Now, if---you were going to make a one piece griddle/main cap that used the 10 bolts Plus the oil pan bolt holes---then doweling the girdle to the block at the main bolt holes would be a route to take----------

With that, I'll back out of the main cap discussion as I have said my piece, speaking from my past and present experience---

I'm sorry, but it seems that every time I get involved in this thread, I probably come across as a nit picker---

No Jerry, noway you can be accused of being a nik picker. We are all here to learn from each other and I know I enjoy watching Steve and his builds come together, I'm sure he will admit that he doesn't know everything the same as myself. If you have experience in your field then I'm sure when you speak up , we should stop and reconsider all angles before the final decision is made. One thing about this site is we are all friends and we shouldn't take any offense if somebody says otherwise against what we think is correct, otherwise how do we learn. Anyway, that is my take on it and I will always appreciate the inform information that you and many other give freely here.
