We want to show you all some of the steps and process that we do while you block is here at ERL. ERL's blocks might be higher on the price but we feel that quality of machine work and the hand time spent on each block is unsurpassed. And if you do a price break down from ERL to any other company after all the machine work is done, usually we are only maybe $100 more in total cost.
We start by removing the stock sleeves and stress relieving the block before we machine it for our Superdeck 1 sleeves. After stress relieving it we put the block onto a fixture and put it into the Haas CNC machine where we do all of the decking and boring for the sleeves.





After installing the Superdeck 1 sleeve we will then put it back into the machine for the second process and final machining process. We begin by using a Probe and touch the top surface of the block. This tells the machine exactly where the block is located in the machine for exact machining to the .0001. To put into perspective of how much a .0001 would be is like taking a piece of hair, cutting it in half and then cutting that half ten more times. We then will machine the block and the head of the sleeves for the block guard to be pressed into the block evenly. We run an endmill around the head of the sleeve and around the periphery of the block. This allows us to get an exact fit of the block guard evenly all the way around the block and the head of the sleeve. After the block guard is installed we then run an endmill in the top of the block guard to machine the coolant groove. Now that the blockguard is installed we will deck the top of the sleeves. We leave the sleeves .002 higher then the actual deck of the block. This is called step decking the block and what it does is act like an o-ring seal. The last process is boring the sleeves several thousands smaller then the desired finish cylinder bore.





















Now that sleeves are installed in the block it's on to the honing. We begin by grinding the caps. We grind the top side of the caps first to get them flat so when we grind the bottom side of the caps (the side of the cap that sits on the block) we know that we are grinding a true flat surface. We grind .003 off both sides of the caps. By doing this it allows us to have material to align hone the main journals and keep the factory journal size. Go to our website and check out our Tech-Briefs and we have one that gets very in depth on align honing and the reasons for align honing.

After the caps are ground and put back onto the block we heat cycle the block to help stress relieve it and it helps seat the main caps back onto the block before align honing. After heating the block we then will stress relieve it once more now that sleeves are installed and the main caps are back onto the block. Later we will retorque the main studs/main bolts and align hone the block. After align honing the block we move on to the cylinder hone. We hold a .0002 tolerance on both align and cylinder hone. This is the same thickness as the average persons hair.















After all of the machine work is done we remove all of the plugs from the block so we can flush out all of the oil and coolant passages and brush them to get any chips out. We clean the block thoroughly in the solvent tank and then blow out any of the chips that might be left in it and the solvent off of it.








Now it's on to the last process and that's a final wipe down, bag and boxing the block up for shipping, or assembly.






I hope this helps give everyone some idea as to how much work goes into each one of these blocks and the quality of work we do. Feel free to ask any questions and check out our website.

awesome stuff guys thanks for posting all the techinal pics.. we were very impressed and still are impressed with the performance and reliability we have had with our H22 we got from you over 3 years ago..

PM'D Sir...
No problem. We want people to see what actually goes on with their blocks once here at ERL.

It's comments like this that really inspire us to keep our quality high and always look for ways to improve. Thanks for running our stuff and choosing us.
That´s why we only work together with them and offer only these blocks to our customers.
Unfortunatly the shipping from Germany to the USA and back from the USA to Germany is damn expansive ...
Customer service is great and they support us as good as possible even over that distance.
