Who IS running C5R heads? I have had this idea running through my head here lately and wanted to see what people were running.
Im doing 402 w/ a eagle crank and rods with diamond flat tops(which will prolly be too much compression, so i'll prolly go to a dished set up to get back around 12:1).... of coarse I'll be doing a solid roller and a sheet metal intake. But my goal is to have one BAD **** streetable engine(must run on pump gas) and then fog it with oodles of nitrous. I'm not looking to break any records but I don't want to be outrun within the state of mississippi(there are a few high 9 second ls1's and thats about it)... I'de like to break the 8 second barrier though.
BTW the block, crank, rods, pistons, and rings are already purchased... awaiting fitting of rings and being sent off to be balanced.

I have some C5R's sitting here...
Problem is you have to renotch the pistons and a 40-48cc chamber is going to have lots of compression so a custom piston is the way to go.
They also like a big bore like a 4.100 or larger.
The block is the only thing holding me back on this ****...

I would look into the new heads comming from ET if I was you. They are geared up for a 4" bore and bigger and flow more then some of the c5-r offerings out there right now.

I don't even like the idea of using these heads due to their small combustion chamber (38ish cc?)
Using heavily-dished pistons to lower the compression is a terrible idea and IMO is like a band-aid.

A Band-Aid eh? Wow, I love the internet.
How about these then....
That's an expensive band-aid to me.... Custom reverse dome pistons, and a welded combustion chamber to get chamber volume down to 30cc.... And to think it ran on 13:1+ on pump gas with no problems... then again that guy who build it doesn't know that much, he only builds 815 cube mountain motors to push guys into the mid 6's at over 215mph. In fact he has the IHRA Pro Stock ET and MPH record with his motors, and the last 10 years powering the IHRA Pro Stock Champs.
Yeah that's a freaking band aid... That's why a SB2.2 on a Nextel Cup Motor (12:1) or a Busch Motor (9:1) does the exact same thing.
And these motors use even less total timing than a LS1 for max power, doing a chamber this way really must suck if you can get total burn to happen that fast.
There is a world out there full of better heads (both cylinder and brain) that makes a ton more power than a LS1 and you could probably learn from them. You picked the right guy to work with on your car there with Futral, so at least you have right idea to work with someone who knows what they are doing, but it would be a good idea to learn what you are talking about before you put your foot in your mouth.
Sorry Man, but I can't let grossly inaccurate statments prevail....End of Rant.

Remember it's a burn not a explosion.... getting the particles in closer proximity to the start of the burn is going to work much better. A sphere is going to burn faster than a pancake if you want to think of it that way.

ChucksZ06,
Not a problem... I might be one of the only people out there to see potential in the GM market, we just need to start thinking better than the Ford guys in terms of technology and not LBF (Low Buck F*^k) setups like a $400 turbo setup that I see those guys do.... I have no problem "ejumacating" guys on how motors work so that we can develop better motors and feed the market. The Ford guys really started this, then the import guys took over and the GM guys now have these awesome motors to play with. Who knows one day we might have Pro 5.7 Racing classes.... lol It would be cool to have a real racing class with EFI motors based on stock style layouts. Pro Stock is cool but those things are so far out there in terms of being a BBC or a "Hemi" it's silly.

Advice you should take yourself before you ask your daddy to answer the questions for you. Don't think for a second I don't remember when you were a newbie on CZ28.com and asking completely retarded questions. I can post examples if need be.
Internet glory. Who loves it?

LOL, funny.... I'm fully capable of answering my own questions but I'm lucky to have a father who taught me some great fundementals of this. Good try on a comeback though for getting owned on a post beforehand. You put your foot in your mouth, sorry your ego can't handle it. Go ahead and feel free to find a retarded question I asked on CZ28.com, I don't think I've ever asked a question, in fact all I do is answer them. If you really want to waste your time looking, sounds like a fun way for you to make a productive afternoon. Or you could work, which is what I'll be doing.
I could really care less about making this a pissing match, not worth the bandwidth.

Are the intake ports (intake manifold-to-head face) a C5R derivitive (ie: will an intake built for a "real" C5R head fit on those etheads)?
