New GM LSx iron block and heads on 1969 Camaro, 454cu in, 641 hp... http://seriouswheels.com/cars/top-19...let-Camaro.htm
Here is a link to the block in action...Reggie Jackson's 1969 Camaro, 454 cube LSX GM iron block, GM Aluminum LS7 style LSX heads, 4bbl LS7 style GMPP intake manifold, 850 carb, MSD distributorless ignition, 11-1 pump gas motor....641 hp and 611 torque. Obviously this is a pretty mild motor compared to what "we" would do with it! Still a nice overall package.
Maybe the GMPP intake could be used with an elbow and 100mm TB.....THAT would be cool with a 101mm rear mount turbo.

I started a big thread on this last night which makes for a good read. This FREAKIN Block is GOING to ROCK and I am PUMPED ABOUT IT and just might go back to a huge cubed N/A LSX Powerplant (where my heart really is)!! 
Here it that thread:
https://ls1tech.com/forums/showthrea...4&page=1&pp=10
Also, Here is the VERY INTERESTING READ on this MONSTER GM PERF LSX BLOCK that reggie jackson and warren johnson dropped into reggie's g-machine 69 camaro and which obviously is running a MILD cam and compression to be making only 641 at the crank (which is still very respectable) and what a GORGEOUS 69 Camaro.
Hmm, this link was working last night and now linky no worky!
Maybe b/c I am in the middle of snow storm in Chicago after just having one full week of 60 degree dry weather!!

Took a second or two to find it on the main page as it was a previous article.
hmmm 12.5 wide rim's stuff'd under the rear...
LSX heads based off of the LS7 (6 bolts per cyl compared to the LS7's 5 bolt per cylinder).
850cfm carb on the GM Aluminum LS7 carb manifold...
Custom Valve Covers (GMPP needs to make those standard not custom).
Hiding the coil packs on the firewall was a nice touch...

I'm very happy with my ls2 402... but when I eventually build another motor.. that is definately gonna be a candidate... only the next one will be 14 to 1 compression, be as close to or over 500 CI, be solid roller and have a cam that has at least 900 lift.. and will hopefully make more power then my current motor will once I get the nitrous on it 
(car will be full race by then I'm sure)
I can't wait to see what these will hold for the future lsx race setups.. this along with the world block will for sure be the death of the sb1 and sb2.

Anyone know of a 4.5" crank that can go in these? I imagine there will be once this bitch comes out but just wondering if anyone knows of anything concrete. I noticed Eagle had a 6.56" LS1 rod available and that SAM was using 6.8" Carillos in their 500" project.

4.5 is a big *** arm to throw around, but 511 cubes is nasty good! 481 cube is perfectly square, a "mild" stroker crank makes 511 cubes..silly!!!!
511 cubes, 400 cfm (ported) heads, sheet aluminum intake, .730 lift cam with 260-270 duration, I wonder if 700 crank hp on pump gas would be easy or simple to do????
God, the torque on 511 cube stroker with those heads would be silly. Probably feel like a 422 stroker on a 150 shot with "shitty" LS6 heads!

If something happens and a bore get's scuffed at that 4.25 your wallets in for a hurting. I'd think a 4.5 Stroke and a 4.125 Bore which also nets you a 481 would be torquie as hell also. I'm really excited about this block. I'd buy one right now if they were available.

482 cubes, 400 cfm heads, sheet aluminum intake....I am forseeing 700 rwhp on pump gas and agressive tune.
I don't know that much about boosted motors, but I think a perfectly square motor likes boost as well, at least more so that a big stroke/small bore does.

I'd say once the block hits the market, then the big cranks will too.

I thought about possibly contacting Callies about a Compstar "Speedpack" they call it. It's the Compstar rotating kit with Mahle pistons plus rings and bearings. Compstar even has lightweight cranks and I noticed their website said a Compstar tall deck LS1 rod was on the way too. Might be able to get a custom rotating assembly for a pretty good price there. I thought about calling Scat and Eagle too and seeing what kinda deal one could swing there. I don't guess I should be in too big of a hurry since the block isn't even out yet, haha.

**** the pump gas.. there's so much more power to be made with an engine this size and race gas... why stop at 700... mine as well go for it and aim for 800+ rwhp on motor
Face it... even an 700 hp all motor setup isn't getting driven every day, probably will only see 2000 miles a year at most, so why not feed it real fuel?
