Re: Great article on N/A 440 cubed LS6 making 700 crank horsepower! That is great... however there are smaller Ci LS6 motors making more crank HP #s.
last one here In Htown was 740 Crank HP. the car traps over 140MPH with a 3400LBS.
But not too take anything fom the atticle.. That is great #s.
C5R heads is capable of 800+ pritty easy but RPM would be a must! or a really big motor... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Great article on N/A 440 cubed LS6 making 700 crank horsepower! Wait-a-minute, thats 630-640 RWHP, that simply CANNOT be done with a LS6 intake and heads.

Re: Great article on N/A 440 cubed LS6 making 700 crank horsepower! Supposedly LS6 heads are flowing in at 350CFM seriously ported. This would get you to the 600rwhp mark N/A.
Not sure if the LS6 intake would support it though, actually the system would flow well under 350CFM with the intake attached.
LS6 with aftermarket short runner high flowing intake should be able to get to 600 or so rwhp n/a

Re: Great article on N/A 440 cubed LS6 making 700 crank horsepower! Does anyone know where you can get these c5r heads, or how much do they cost if you can even buy them. Also does anyone know what kind of compression they were running to make 700+ crank hp.

Re: Great article on N/A 440 cubed LS6 making 700 crank horsepower! Im sure some of the flow is related to the bigger valves not shrouded and spread apart when the combustion chamber is initially designed with a 4.125" bore in mind.
I think its safe to say that these heads would not work well on anything smaller than a 4.125" bore.

But its a few HP higher than the standard 427 LS1 ~525 rwhp from most sponsors. I know of 3 MTI motors that dipped into the 9s without all that C5R stuff. But then at those HP levels, I suppose you understand "diminishing returns". We'll seen how MTI's new solid roller C5R-headed car does and then determine if WCCorvettes managed any hattricks.

Re: Great article on N/A 440 cubed LS6 making 700 crank horsepower! VISERAL:
I believe the MTI C5R solid roller car that you are referring to is none other than THE COLONELS F BODY, which was the first LS1 to get a 9 second N/A time slip with its older MTI 422 Z07 LS1 stroker with the same hyd. MTI S1 cam i am running, with specs of (244/244, .612 lift, 112lsa).
When the kinks of that motor are worked out that WILL BE A BEAST of an ENGINE no doubt.

Re: Great article on N/A 440 cubed LS6 making 700 crank horsepower! MTI C5 Roadster: 700hp with a C5-R block is nothing impressive at all... especially when your forking over 20g minimum on the motor. For 20g you should be able to build a 2000hp turbo small block. HP/dollar wise your right up there with ricers who spend 15g to run 12's in their FWD monsters. <img border="0" alt="[judgement]" title="" src="graemlins/gr_judge.gif" />

1400 hp perhaps.
Duttweiler would want 45-55k for an 1800+ hp rocket or bowtie block with motec and a couple of ball bearing T-76s.
just an aside, I suppose.
427 MTI: Yeah, I know who it is...I just never know who wants what said around where... so I just say what needs to be said and leave it at that <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> .

You would have to be slow in the head or really rich to pay 45-55k for any motor... I don't care if its a 900 cubic inch mountain motor either.

Re: Great article on N/A 440 cubed LS6 making 700 crank horsepower! You said small-block. I dont know anything about building turbo motors other than SBC's, but I cna assure you... 2000hp SBC is not 20k$.
Lets say you went cheap-
Bowtie tall-deck block machined 3500
LA Enterprises billet crank 2700
Oliver billet I beam rods, good bolts 1200
JE custom pistons 1200
Canfield ported aluminum Edelbrock 256cc heads
with titanium exhaust valves 3400
Jesel shaft rockers for 18 deg heads 1100
Jesel belt drive 600
custom solid roller cam 260
pushrods and lifters 400
O-ring machining and gasket for HG 400
arp head studs 350
Custom Hogan sheetmetal intake w/tb 3000
fuel rail/boost ref. reg. 700
160lb/hr injectors 600
Motec computer w/ wb sensors 5000
custom oil pan/dry sump 1000
misc. gaskets, work, etc 500
-------------------------------------
thats $25,300 for just the *engine* and doesnt include the good turbos (ball bearing T-76s are muy spendy), custom spearco intercooler and plumbing by a good house, etc. and then hours of tuning at a good shop.
Theres a reason why when at the end of the season Duttweiler offers spare turbo SBC engines for 35k$, they get snatched up within a couple days. And what I put up there is the basic way I'd do it. I think skimping on any of those parts would lead to failure.
And what would that engine above make on a good day? 15-1700. 2000? That would take some ***** and a few spare engines.
And then what could you put behind it? Nothing but a glide or a lenco/jerico setup. And just how streetable are those? ;-)
I still have an extra set of the 4.125" JE custom pistons from when I did this last. I'll sell em cheap <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Great article on N/A 440 cubed LS6 making 700 crank horsepower! not quite sure how anyone can say 701 hp NA is not impressive. Hemi's made 650 hp? What were their trap speeds in stock form? Surely not enough to be putting out 650 hp. I am a fan of Hemi engines.
I love to hear about these engines. Too bad everything does seem so expensive.

Re: Great article on N/A 440 cubed LS6 making 700 crank horsepower! TERRY BURGER:
Man i can't believe you haven't sold that beast of an engine yet for 7K. I think that is one heck of a deal and surprised this hasan't been snagged up yet.
Best of luck on a sale in the immediate future. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

Re: Great article on N/A 440 cubed LS6 making 700 crank horsepower! A C5R block have alot to do with the power your motor can make without spilting the block. The C5R block can hold over a 1000 HP easy. I don't know the max HP onit.
