Anyone ever heard of that term before?? If so, can you explain to me what is done in this process?

There is a machine shop that is experience with building many V8 engines, as well as Sprint Car race engines...Drag engines, etc...
They do plenty of work on imports as well.

I was really curious when i saw this "filling" term on their website. It just says this, "In specific applications, our short and tall block fill is used to stable cylinder flex at higher RPM. Poor cylinder stability increases ring leakage and decreases horsepower. We use our own proven blend of fill to add horsepower, strength, and reliability to your block and engine."

Any thoughts? I will be calling them later today, just wanted to know what you guys thought!!!
Peace

:edit: maybe this filling is ONLY for V8's because i've never heard it before. They also only charge just under $300 for parts labor etc...:edit:

I have heared of that term before at the local machine shop but the only thing that sparks in my mind about it would be, I guess back in the day they would fill the blocks with cement or a tough liquid like cement that would can be pored in between the cyliner walls to make the blocks more sturdy and prevent cylinder bores from cracking..

Now sure you would loose cooling capacity and probably in fact you never even put the coolant in the engine after it, but than again they only used this in the drag racing applications where you would start your car run it and shut it off so wouldn't really give the motor enough time to heat up.

And of course the cars would never be street driven.... But who knows I might be talking about something different here....

P.S. Earl should be able to clariy this term I hope...

 

Could they just fill in sections around the cylinders and leave some water passages?

 

there is expoy resin that you pour and actually can drill out the holes for the passe and still be okay for water flow it kinda makes it solid block

 

Are there any problems with this technique of reinforcing the block? Why isn't it more popular if it is cheaper?

 

So maybe this wouldnt be good for a daily driver...unless they do drill out passages for cooling...

 

cooling is substantially decreased

 

Just called the place and asked him whats the deal. He said its for Drag/Race engines only..

They do use darton sleeves for sleeving there i guess...So maybe i'll consider that i guess...

thanks for the help guys
Peace

 

I've heard of this before...people actually filling the bottom of the block with wax, pouring in the resin, and then after it cools drilling blockguard-like passages and melting the wax out with hot water. I think on our apps it's still a little better to resleeve...I mean does anyone really have issues with cracking or distortion once a block is properly resleeved??

Yea that's true, but I think block filling costs less than half as much as resleeving. For people on a budget and won't boost that high, it can sound pretty attractive.

 

has anyone done this? i found a write up on another site...

Just like closed deck sleeves.

A pound of Devcon F-2 liquid aluminum epoxy costs $42. I am happy to fill anyone's block, for those that will pay me a little less than half what sleeving runs.

You use salt to determine the lowest point you want the epoxy; that way it dissolves and can be flushed out of the coolant jacket. I'd hate to see someone try wax, and the problems getting rid of all that residue.

As far as boosting that high, HMT's Beau was hitting 470 whp on his B16. He logged a little over 200 1/4 mile passes on that engine, and sleeves are still fine in it. *shrug*
