429 restoration

[Matti Roth]

Hello, and thanks for adding to group!

I am restoring 1964 429 engine which I bought as dismantled. It is said to be smoking in driving and has been stored as parts for a year. It is most probably 65500 miles driven. Car was not driven for10 years.

The only damaged part found so far is the top of exhaust valve of cylinder #5. The top has been worn so much that the rocker has been pressing valve locks as well. Respective rocker is worn as well, much more than others. And exhaust rocker #6 is worn as well, and exhaust #8.
Then questions:
1. What damage could this cause? I can think that valve lift gets a bit smaller than it should, but so what?
2. Is that common for Cadillac 429 exhaust valves to worn from the top, especially cylinders #5 and #6? Maybe there is less oil.

This is my first V8 engine project. I have Shop manual. I plan to replace piston rings, all gaskets, nylon timing gear, some worn exhaust valves and rockers, and valve stem o-rings. Bearings, pistons and shafts are in good condition. 

Big thanks in advance!

Thanks Mark!

I was wondering what is that grey stuff here and there. It is not only those long bolts but in many places in heads and the block.  The bearings do not look much worn though. I need to check the bearing clearances. The block has been cleaned by engine shop, the heads are not yet cleaned.

Could that grey stuff be some kind of anti-seize material used by previous owners? There is no grey stuff in oil pump and not in oil pan. Cam, crank and bearings are in good condition.

Getting there, slowly but surely. All pistons in place and timing chain. Next timing chain cover. There are two broken bolts so need fix those first.

Started to rebuild the heads now. I will add those valve guide seals, even though there were not originally in 429. O-rings in valve stem are replaced.

I noticed there are no dowels for heads in the block. 
Are those available somewhere? Maybe using suitable roll pins?

I have found dowel pins at Ace hardware before.

You shouldnt use a solid dowel pin, that hole is used for oil return from the head so the pin cant be solid.
I have drilled out my own a bit to increase the return flow

Thanks Jan, good point! It is hollow for a reason.

I am using roll pins as a dowel.

i need these guide pins as well, can you give details on where you found them? What size they were. It looks to me like they are .010" under a 1/2"

[Matti Roth]

Hi Rick

I used 1/2 inch roll pins which is pressed when pushing to hole. They sit very tight.

I have not yet completed engine rebuild but I don`t see any reason why it would not work.
