Playing with Blocks! An early 430 Buick Friday Block? Strike Block? IDGAF Block? You tell me...

- We start Oil Mods on an early production 430 Big Block Buick and find a few things that are interesting while looking the subject over and decided to try and figure out whats happening and why with this early production engine. I discuss the major differences between the later 455 big blocks and this early production 430 ND stamped block. #NoNameNationals
Hydroscopic is the word I was looking for…. Get to work brain! Lol!

me too! lol!
I drove a 430ci for years and years with tremendous oil starvation and it just would not break down on me. Pickup tube in the pan was all clocked up. Barely any oil noticable under the valve covers, left side was 100% dry. I would have rebuild it just as it came from the factory, no modifications needed. Instead i only cleaned it and re-gasket it.
Well my cousin had a 67 wild cat 2dr. And for a big car it used to get down that was a fast car it would whip a stock 383 road runner with no problem for a big car it was a brute. But the thing that had my cousin puzzle is if you would do a fresh oil change on it it would always come back a quart short. So he took the car to the dealer and they told him the technicians explained to him that that was a test engine for that year only but I have a 81 Cutlass and I had a chance to own a 4:30 wildcat 67 Buick motor but I passed up on that deal and I live to regret it because the motor made 360 horses at 475 torque. Factory. But anyway that's enough I don't want to rambling because I can go on and on. NEW Orleans ✌️
I had a ‘69 riviera as my first car with the awesome 430….that car was bad ass
My twin brother and I shared a 68 wildcat as our first car and it was amazingly fast for a boat of a car that but it was, and it too had the 430 in it.
@@kimdearrington258simply one of the best engines of its time.
I know the physics behind the design of the pick up side of the feed hole
Maybe that block was made on a Monday morning or a Friday afternoon. 😄 Nevertheless, I'm sure that you will work your magic on it to make it more suitable for greater HP/TQ use.
The 430ci is one of the best in its time from the factory
Great videos. What do you think about the second oil passage to the rocker shafts dead-heading at the block deck? The dealer where the person I bought my car from went back and plugged the oil passage in the head with silicon and a horshoe nail shortly after they bought it in 1967. It is a 430, just like yours. The question is why is the block not drilled to connect with the head? By the way mine showed considerable wear on that 'dry side.'
I’m not sure what you are asking me. The 430 has a drilled oil passage on both sides of the block that comes directly off of #1 cam bearing that feeds the rockers through the passage in the head and the front rocker stand. I’d unplug any hackery that has occurred in the past and is likely what has caused your wear.
@@mr.roddersneighborhood2740 That matches, for sure. Yet, the thing that baffled both the machine shop I use and me was how there is an identical oil passage on the rear rocker shaft stand. But, it is unused and dead-heads right into the block deck. You can see the 'witness' mark on yours in the end of your video.
The best the toolmaker and I could conclude is that it likely reduced top-side oil pressure and was scratched after the fact. The reason for the recall and subsequent nail and filler in that passage in the head was concluded to be preventing burned, stagnant oil trapped in the passage, which could block the already poor oil amount to the rocker shafts.
What I do not know---yet---is whether or not there is a corrosponding passage in the block casting that could connect to the head.
Oh, and the other theory was to keep costs down and use just one cylinder head casting. I guess I can see that.
That’s it right here. It was to make the cylinder heads interchangeable on either side of the engine. You do not need the oil to circulate, just flow through the rockers and out the tips of the rockers.
@@mr.roddersneighborhood2740 Well, it is that. I see. That sounds like the passages should be blocked, afterall, to avoid the burned oil in the passage problem. I think I will use some metalic JB Weld. It seems a bit less invasive than tapping and plugging. Thanks for your responses.
It was only Friday. Friday. But Sundays a commin'...

Boring that oil pickup hole bigger would weaken the block.
Sure it would, but every single 455 after 1970 had this oil passages increased in size due to lack of engine oil. So one way weakens the block and the other smokes the bearings. Choose your poison.
