Does anybody know or heard of what happen too the CNC Aftermarket V10 block that was suppose to come out? I think I remember a thread on here a couple years back talking about it being in development. Does anybody know the specs, CID, or horsepower potential these blocks would have??
With the viper block already making killer power and holding up well I could only Imagine What new windows this could open up.

When talking about a block....one should not use the word "window"
Shit....I don't need to know as the block itself will probably be 20k...a billet crank is in the order of 5k+
To your point - I beleive it was Indy Cylinder head that was talking about it.
Thanks for the responce BIGRED.
I guess this would be for drag racers who wanted serious power.Kind of like how the LSX and Warhawk block is made for the vette and f-body crowd. Some of those blocks are rated for 2500hp. I would imagine if someone wanted to push a viper in the low 7's or maybe even a high 6 this would would be a good choice. Come to think of it, I don't think any one has found the limits of the factory v10 block yet.
Yes DC and it's racing program did an awesome job to say the least with the whole GTSR car right down to the last block
Now if only more were available out there...
Having been involved in building an aftermarket block for Carroll Shelby I can say it would not be to hard to build Viper GTS-R type blocks. It took about 1 year and $100,000 to build the 1st 10 blocks. Selling them at about $5500-$6000 each you should make your money back in about 100 blocks. Shelby is right at 1000 block produced starting in 1996.
With CNC billet wet block technology - casting a new high performance block would seem to me to be redundant now. A billet block offers so much more, and for the ultimate engine - is worth the cost. All it would take is someone to determine the end design, program the software, and buy a bloody big lump of billet. All waste is recycled.
A cast iron block will leak down far LESS than an alloy block.. this is why you will see most drag racers use an AFTERMARKET iron block when they want max power and do not have to save weight. An iron block is worth from 20hp on a stout small block up to 100hp+ on the monster motors that twist themselves to pieces (tho better new casting designs are improving on that).
Even the best alloy cast blocks cannot run as tight a tolerances, seal as well or make us much power as the same casting in iron because of the distortion under heat. Hot hone helps as does special ring prep - but you can do that to an iron motor too and it will still make more power than alloy.
How does a billet block compare? Well they share the light weight of their cast aluminum cousin (can be even lighter), they are much stronger and stiffer given same basic specs, and they do not flex or distort as much, in fact engine builders can run close to iron block tolerances on them for this reason! On top of that they can run more cooling water as there is far less limitation. Water jackets are machined in from the sides and sealed with o-ringed panels... means they can disapate even more heat.
Conclusion: billet alloy blocks will be the future money block for the serious street engine as well as all out race. CNC Blocks make em, and Dart do one for the LS1-LS7 for the ultimate Chev small block.

with the power some of the big dogs make around here on a stock block im amazed nobody broke one yet. id just wait and see if a stock block ever breaks. once someone breaks it, then worry about getting a stronger one

that is fair comment - though for me - anything over 540 cubes and boosted would cause me concern. The block may not let go, but will move enough to require regular rebuilds. Going big bore is just a bad idea IMHO, and the big stroke is only any good if rpms are kept down as you can only get so much rod in there.
At 488-510 cubes - the block is not likely the limiting factor on pump gas - though a billet block would add power and durability.
Sonny's has always seemed to turn out some pretty high quality stuff. If they wanted to, I'm sure with the equipment and resources they have that they could make a head that rivals the JM set ups. The promo vid was pretty cool, some expensive machines in there thats for sure.. but if you want it done right...
