  The day started off pretty cool it was snowing, unusual for here at 1000 ft
WE got the rods and rings on the new pistons and all ready to install in the block. Then we opened the new rod bearings and discovered they were way to small? They sent bearings for a big block chevy, not a 426 hemi rolleyes. The mains were right and the writing on the box saying chevy was so small I couldn't read it without a magnifying glass.

Had to modify my original post because I was told my photos were not properly posted.  So here's a second try grin

Photos of our pistons and rods installed.





Cam is placed and all a whole lot of studs installed.



Timing the cam.



Cam is timed and the balancer and magnetic pick up is complete.

Thanks Stainless!  I couldn't put the oil pan on yesterday because I had to wait for some silicone to dry that I put over two small bolts on the rear main seal.  The silicone was dry today so I could shave it down and put the pan on.




We took the heads apart so we could check the valve and lap the seats.



The exhaust seats are a bit smaller than the intakes. shocked



Beer time.

Do you  do any type of sealing check on your valves after lapping ??  Like  some type of liquid  or a vacuum hold or leak down  and if so what percentage leakage is acceptable .  Are your seats done by 3 angle cut or stones ??  THANKS   STEVE

3 angle cut and gasoline for leaks, outside the shop :- No leak down.

 3 angle on intakes only with narrow seats, Exhaust are Inconel with 3/8 stems and 85 thou on seats.

 It's a 2 angle on valves with back cut and seats are about 60 thou.

 Last head is lapped in and assembled and installing heads tomorrow.

This first photo shows where we put the high temp RTV silicone.



We also duplicate the same areas of silicone on top of the copper gasket.



Heads are torqued





And lastly the manifold.

  Crazy.... I ordered some valve cover gaskets Monday and got email today with USPS tracking #, says delivered and left behind fronT gate [which was open, too hurried to drive 800 ft to house] at 9:27 Am Wed. I left at 10:35 Wed not knowing about so called delivery but no package was there. I got back about 12:30, no package really not expecting it yet. So today I checked tracking and they say out for delivery huh How could it be out for delivery if it had already been delivered? Any how I left again thinking I would have to report a porch pirate theft, stopped at my mailbox [ several
boxes of steel with big boxes for packages, they leave a key in your box with # to open big box] anyhow package was there rolleyes

 But wait there's more.... I didn't like the looks of the gaskets. I tried to order the normal Fel=Pro gaskets thru Summitt but no listing for any hemi.

 Ok so I looked up FELL-Pro site got #  which I had lost went to Summitt site put in # and they had it.

But searching for it shows no valve cover gaskets for 426 hemi?

  Being shipped

  We started to adjust the valves and had a problem with a couple of adjusters. Over the years we've ended up with
3 different makes so I finally figured out to contact Manton pushrods they make good ones out of tool steel the right
length with hole in center, Expensive little devils but should last a long time.

 Got the valves adjusted and after fixing a slow leak from an oil drain back fitting on cover, I got the valve covers installed

 Install flywheel, clutch, bellhousing and first unit of Owens trans and engine will be ready to install.

  4 am... had nightmare about coming across female relative and friends driving my new truck so  blitzed they would wreck it in the next 10 ft. Anyhow couldn't go back to sleep,so Beer and left over pizza grin

  Troy pressure washed the engine bay, midplate and bellhousing yesterday and we washed the car..

  We also made up a timing indicator that mounts on the block and goes across the timing marks on the dampener
installed spark plug tubes and warmup plugs.

 New paint in engine bay and installing clutch and bellhousing next.
