Swedish Mike Posted August 25, 2006 Report Share Posted August 25, 2006 Yeah, I looked into this a few years ago but decided to leave it as a wish after hearing the price...A engine company here wanted 25.000 USD to make a custom billet steel block.How much does it cost to have one made in USA? I´ve seen a few billet V8 blocks and even Honda./Mike Link to comment Share on other sites More sharing options...
blkaplan Posted August 25, 2006 Report Share Posted August 25, 2006 Why would you want a steel block?Aluminum is very stiff and quiet good in block applications?I dont think you would gain much strength by going to steel.....Unless you got it heat treated,,, but then again you could aways get an aluminum block heat treated...

Cylinder walls and area around it moves too much.People have tried most solutions to make it stronger but all failed, if you fill it with block filler or a plate they brake between the cylinders instead.The head is bullit proof, never any problems. Same with crank.No idea to discuss it, a new block is the only way to go. /Mike Link to comment Share on other sites More sharing options...
Gioseppe Posted August 25, 2006 Report Share Posted August 25, 2006 i've seen some honda blocks go for like 4k, try contacting those companies here in the us about a special application. Link to comment Share on other sites More sharing options...

A buddy paid around 8K for billet alu big block, pretty ok for a huge block that handles 3000 hp. /MikeEdit: Wish we had Honda prices on our parts... http://www.raceeng.com/pc-4642-67-dart-hon...0x84mmtall.aspx Link to comment Share on other sites More sharing options...

Heat treating and aluminum can work wonders...What type of power levels do the blocks seem to fail at?What about a sleeve/block filler combination?

A properly machined steel block would be a great deal stronger, however the added weight and cost might not be worth it. :) Link to comment Share on other sites More sharing options...
Gioseppe Posted August 25, 2006 Report Share Posted August 25, 2006 What about a sleeve/block filler combination? oooooooooo. i know chuck was having darton make him a couple sets of sleeves, so hit them up! Link to comment Share on other sites More sharing options...

Heat treating and aluminum can work wonders...What type of power levels do the blocks seem to fail at?What about a sleeve/block filler combination?They break around 800 hp, there are a few guys trying to brake the record but the block always fail.Tried sleeve and filler, strong but over heated and still weak between cylinders, can´t fill there./Mike Link to comment Share on other sites More sharing options...
Swedish Mike Posted August 25, 2006 Author Report Share Posted August 25, 2006 oooooooooo. i know chuck was having darton make him a couple sets of sleeves, so hit them up!Only way to make it really strong is to go down in bore and use thick sleeves. Around 77 mm should do the job but the head wouldn´t match and would need to go down in valve size.We already thought of all this. /Mike Link to comment Share on other sites More sharing options...

Swedish Mike Posted August 25, 2006 Author Report Share Posted August 25, 2006 custom block it is!Unfortunatly... I even went to a alu casting company in the middle of the night and filled a block with melted alu. The block warped and had to throw it away. /Mike Link to comment Share on other sites More sharing options...

EricF Posted August 25, 2006 Report Share Posted August 25, 2006 Mike, I would guess that the cheapest solutions will be companies who outsource plans to China, and there are probably innumerable companies that do that both here and over there...Talk to Sten Parner and see what he suggests? One company in the US I know of who makes blocks for some applications is www.dartheads.com though not sure if they do custom applications or how affordable they are.Mike, how about boring the blocks way out, filling the block and welding deck closed, get real sturdy thick cylinder sleeves and smaller pistons? Lots of companies make cylinder sleeves, sure you could get some custom made that will solve the between-cylinder cracking issue... Link to comment Share on other sites More sharing options...
