this block has been "pinned"...supposedly Larry fron Endyn has been doing it for years. The owner of the block got 400 horses from it. Anybody ever seen this before? seems like a cheaper alternative to sleeving, and better cooling than a blockguard.
or ???

that is also known as block posting

Personally, I would sleeve or use a block guard but block posting has worked for many people in the past.

 

looks like an alternate way of doing a block gaurd.......

 

i havent seen a block like that in a long time

 

I haven't seen a block like that from Larry. His normally look like this:



That's my block that Larry helped me post. The sleeves haven't seen boost yet, but I've got about 1500 miles on the engine and no problems with coolant leaks, oval cylinders, etc.

Seem's like a nice concept but you still have the stock thickness of the OEM sleeve i think it would be good for low boost app's but i wouldn't trust it for any high boost. just my 2 cents.

 

personally i wouldnt run that set up. i dont like the looks of it, it seems like an old way to do things.

I would trust Larrys judgement 100%, he's been doing this i think for over 20 years! Think about it like this, if he sucked or did things wrong, why would he still be in business. Here's some shots from my block when he was working on it.

 

i would have to say that posting your block like in the first pictures is a very bad idea. you are taking away metal from around the outside of the sleeve, making it weaker. even if you are replacing it with an aluminum post, there is still space in between the two, since theyre two separate pieces of metal. you are weakening your sleeves if you do this.

i was talking about the pining of the block, does he still do this??? id be surprised if he did...

your block doesnt have that done, how do you know it can be trusted???

Landon

 

give him a call and ask him what he recommends

By the way, its 250 shipped to my door

I an assure you that these pics you posted are not the work of Larry.

 

so am I making a mistake with this block?

 

I wouldnt get it. I can tell its not his because he posts his blocks like how sonny showed up above. Plus he doesnt like to have anything on top of the sleeves to keep coolant there.

I dont think Larry would put his name on that one. I have seen the quality of his work first hand and that definaltey isnt something that falls in that catagory.

 

it wasnt' from larry, its just something I've heard the larry does...apparently he does it differently.

You are correct. A weak spot(s) is being created where each of those "pins" are located. I learnered this in my Machine Design class in school. Now this sleeve is more prone to cracking where the material from the stock sleeve has been removed.

 

liblah libalah timmah

 

timmah?

 

retarded kid on south park. Timmah! (timmy)

 

lol!!

 

I think pinning addresses the problem of shifting sleeves, without the cooling issues that go along with using a block guard.

As for this being an "old" way of doing things, get your head out of your ***. It's not like building internal combustion engines was invented yesterday.....

Btw, as others have said, that is not an Endyn block, nor is it even pinned. It looks like someone built their own style of blockguard.

Yup.


First method displayed is pinning, the second method displayed is posting. I'm not a huge fan of posting. I've seen a couple of posted engines that came apart. Face facts and accept that the stock sleeves, which are ribbed and 0.060" at their thinnest, are going to swell under large cylinder pressures associated with big power turbo setups. When you place a post against the sleeve, at some point it restricts the bore's ability to swell and causes the sleeve to crack at 90 degree angles to where the post contacts the outside of the stock sleeve.

Don't take any of that the wrong way - I feel that block posting is a valid method of liner reinforcement, and an intermediate step between stock block and sleeves. It's just not good for as much power as some people I've talked to think that it is.

I used to work at Endyn. I know larry well, and THAT is not larry's work. he is against block guards becuse they don't allow coolant to reach the top of the cylinder. "pinning" is an old light weight trick used in racing that works very well. I have seen exploded blocks where the pins are still intact. It also does not remove any material from the cylinder making it weaker as previously stated.

 

i am sorry..you have me all confused now it is called "posting" you got me saying pinning...it is posting.
