[George Miller]

Using chev V8 roller rockers.

George,

That's an interesting block the head is sitting on.....is that your doing?

As you can see its a 4 port. Built it a couple of years ago. I'm going to use this head on that block for now. Later on will build a new engine for the over head, then put the four port back like it was. It runs real good.

Also for you CNC guys a picture how we put on radius in the old days.

George, Nice job! A really nice job! However, What breed of cat is that machine? It looks like a Bridgeport column, but I don't recognise the head. It's not a "J" and certainly not a "M". I left the trade in 1983 (My Back went out from all the leaning) So there's a lot of new stuff I'm not familiar with. CNC was just getting big then. Yep, That's how we did it! With a turntable and lot's of cranking!

nice job george

That was the shop owner's price. The guy actually cranking the handles and making the chips did get anywhere near that. Trust me!

PS how was the New Hope show after I left?

It was a NC hydr Moog in its first life. I changed it back to manual screws. The main parts were made by Bridgeport. I got it for scrap price where I worked.

ashame you couldnt hang around longer but it was nice meeting you. i got first and my friend took second. i was supposed to go sunday but with the threat of rain i bagged it. the next big show is buckingham in sept try to go alot more cars.

Well the head is almost done, waiting on some O rings so I can put the two halves together. Then put in the valve guides and valve seats, plus the studs for the rocker arms. But I need to mount it on the block to get it in the correct place.
I will post a picture when that is done, Will need a head gasket to get the push rod length.
Larry it is going to be real close to 80 hours. It would be a lot cheaper to just by a head from you.

Here is a picture of the head on the engine with intake manifold.

George,

Looking good! Did you think about turning the carb 90% to balance the mixture front
to rear?

Dudley
PS....you need digitals, I quit counting 20 years ago.

No did not think about doing it that way.
I had to save the money for the head so digital has to wait.

[George Miller]

Well I started the engine today for the first time. So far so good. Will do more with it Monday.

[George Miller]

If you look close you can see the smoke off the headers.

I get more impressed every time i read the updates. If it were me doing this i would not even be concerened about the hours. I would just be focused on the final job and knowing i did it myself. Thats got to be a good feeling when you tell people you made it form a hunk of aluminum. Fine job George. Mark.

[George Miller]

Well I did not get to take my speedster with the new head to the hill climb. Did not get all the bugs worked out in time. It is running fine now, will take it in the spring.
I ended up taking my blue roadster with the olds 455 head. At practice it ran the best time it ever ran 9.33. But then I broke a crank at 5000 rpm. It bent a rod and broke one of my new pistons,bent the oil pan. but did not hurt the block. Have another crank all most done.

I'm sure this is Apples and Oranges but we ran an 8.8 at the 66 hill climb with a Winfield flathead with dual Winfield carburetors . I haven't broken a crank since I installed a SBC dampener. I said Apples and Oranges as the grade is probably different as are the internals of the engines. But I also haven't found the need to turn the engine that high. This time computes to 3640 RPM's. This was with 5.30's in the rear end.

[George Miller]

Was ask some question about the head I made. So the easy way is to post this.
