Quick-- (nice nick by the way) ---
I'm pretty sure that Crushah is my customer and he's talking about the motor and heads/cam combo that Ai and I (sounds funny....A I and I), are building for him right now.

I have the combo specs shown below in the link...
I need to make sure this post is not taken as an advertisement for Ellwein Engines. It is designed to show the FI LT1-383 engine and heads/cam combo that Crushah spoke about--(low compression motor with greater than 500 engine dyno horsepower). The old veteran engine builders will quickly notice that I'm very new to engine building but you gotta start somewhere. I'm all open eyes and ears whenever I'm around an established builder and appreciate all info given. By the way, in your spare time check out Mark McKeown of MME. He's been an Engine Masters finalist the past 2 years. Link to Engine Masters magazine

It's 540 fwhp peak at 6000rpm and 520ft-lb at 4700rpm. That's uncorrected raw data from the engine dyno at McKeown Motorsports Engineering and with a duel plane LT1 carb intake manifold and no accessories and open headers. Crushah is duplicating that existing combo and the power is in the Ai heads and the cam and valve train component selection. (the actual motor/shortblock is dragging down the big power potential due to the heavy rotating assembly and low static compression ratio)

I was happily surprised that it made that power and my goal was 500fwhp.
For being a very very heavy duty piston/rod combo designed for massive forced induction I was also happily surprised at how nice that motor ran on the street without the blower. The Ai cam is designed for the F2 blower that will go on the motor but also for street and endurance and cold Swedish days/nights. It's a net .600" lift solid roller with PSI springs and Xceldyne machined titanium components. The heads are very well done and the valve train is quite costly. I have a web page of the build for the motor combo referenced. Link to that motor build page

Of course now that I look back I hope if that motor had tuning time on the dyno, (and with Mark McKeown's help) that it could make more dyno power than what it made for the integrity/soundness pull shown. Here is a link to the video of the motor in question. (please right-click save-as 9MB file)

I went to the build page, very nice writeup and pictures. Clearly your attention to detail is top notch. So the 540fwhp on an M6 is ~460rwhp with 8.8CR with a carb'd intake, I wonder what power you could make with a SR 12-12.5:1 setup... 525rwhp?

 

nice motor, and +1 on the attention to detail

but lets be serious here, that is a race motor and must have cost a fortune. the op asked about having a h/c setup which is far from this motor, i really dont believe this belongs in this thread at all

maybe you should explain the cost of building a motor like that so every new guy on here does not think he can just slap a set of ai heads on his car and make 500hp

 

Thanks! I'd love to find out what something like an LT1-383 with SR and 12.5:1 and Ai top of the line heads could make rwhp and fwhp. My plans are to get down to North Carolina and test some of my basic short block with as many Ai heads/cam combos as possible. (lofty goals with little time and little money)...

I do know that Ai has 200cc GM LT1 heads on Mike Harris' 383LT1 and although it's higher static compression ratio, (13+ to one) it is making 500+ rwhp through an ATI 8" and 4L60E in an Impala SS. That is jaw dropping wide-eye power.

So to the original poster, as everyone already mentioned, it's a lofty goal for 450rwhp but some have achieved it. It will take a lot of attention on your end too for getting the engine install and combo (gears/tranny) right and fixing any wiring or sensor gremlins.. It's fun though and worth the effort in the end.

Bull's eye!!! that motor cost a ton and is not a heads/cam 350. I think you are right and it is not really topic related but the info was requested to explain the set up. It does have relevance to the heads/cam quality in question of the original poster though as in if Ai should be considered.
So that the OP knows what kind of money it takes to just get blower motor at 500+ (unblown) dyno horse power, it's more than $10K (can be done for cheaper but the owner of the motor wanted premium parts like the custom Callies crank and custom Ross pistons $$$)

I don't mind deleting the post if the admin/moderators think it would be best to do so.

I think by posting up about the price, it clearly shows its an expensive setup and one that most people dont go for. I think the posts were of value though, especially the links.

 

DAMN!
That is serious power. Any times for it yet?
