Settle in on a cam and choose compression to work with overlap....that is, the more overlap, the more compression it will tolerate, hell, it will even need it. A small cam with 2 deg of overlap would surely detonate with pump gas, but with 40 plus degrees, u better have at least 12.1 or it will be lazy on the bottom end. It's not about compression or cams, it's about COMBINATIONS

That 500ci ERL would be simply AWESOME if it wasn't so damn expensive. Its just way too much money, if you plan to use the regular top end stuff (LS7 heads, LS7 intake, FAST intakes...etc..) all you're gonna get is an engine with just a little bit more than a run of the mill built 427ci-440ci.
There's a guy on here with one that makes only 650 RWHP, thats a joke for a 500ci engine. Its gonna be a very fast car, no doubt...but for 500ci.....lol
You can build a 454ci LSX for half the money or less....and make MORE than 650 RWHP with the right top end and not spend near $25,000.
Its 100%, all about the intake and heads. Cubes are meaningless if they can't breath.
"There's no replacement for displacement".....well displacement means nothing with the right top end.

650 HP? LOL that is a alot for a street engine. Considering the fact no one has tried to really push a superdeck II further than a "street engine" sooooo where are you going with this...? ERL has made around 650 on their dyno. The 500 CI from ERL has basically what would be considered a stock camshaft for a 500 inch motor, turns less than 7K RPM. GMPP L92's something around 10.5:1VS
454 with radical cam(prolly wont idle well), aftermarket cylinder heads ported above and beyond some production L92 castings. big dollar intake manifold and Im sure it sees more than 6200 RPM. And there you have it, MAYBE it might see 650hp on an engine dyno.
LOL I really CANNOT EFFING WAIT to see the day they really do a MAX EFFORT 500 CI at ERL Performance!!

My question is why in the heck would ERL build a 500ci motor and dyno it with basically stock top end parts? Built to the hilt bottom and stock top? WTH! That gives us no idea what the thing can do other than guess.
What really sucks is the header issue. Custom headers?
Try putting a tall deck in a Vette. I am sure the intake won't clear the cowl. It's all up on it right now with a stock deck!
I would love to build one but I don't want to be the guinea pig.

The hood would not be the issue. It's the cowl. Not much room there. If they have done it then I guess it will clear. I am curious to know about the headers and the accessories. The power steering bracket bolts to the head so it should move it some what but shouldn't cause a problem. I would think it would need custom headers.

Well custom to me isnt that hard I go to my buddys fab shop borrow whatever I need or take him to lunch maybe give him $40 bucks for supplies and WAM custom whatever I want... I believe ERL had a complete Mach pulley system and I also believe they are trying to taylor these engines to the older Corvette croud, with that being said I want one with more compression, better induction, and making around twice what it is now on power!

They actually did not need custom headers. They used their engine mount which lowers the engine ~1". The headers fit. The X-pipe needed to be modified, which "sounds" a lot easier to work with than having to modify both headers to fit.

I would think the issue was the cowl having to lower the engine. With my 2 inch headers there is no room for movement. I had to clearance the tunnel to make mine fit without hitting. I bet they used a 1 3/4 header to make it fit. Will have to call to find out.

) is if that 500ci set up would hold up with a max effort build, they would have done it already OR thay have done a max effort build (under wraps) and it did not hold up. Either way, until it's proven that the set up will hold up under a serious build it's not worth speculating about it. I mean, c'mon-what are they waiting for? You can't effing wait? Why are THEY waiting for? Like people wouldn't be lining up to buy a 500ci LSX if it was a solid base for serious hp?? Would be a badass sonofabitch if it DID hold up-that's for sure!

LS2 500CI STREET/STRIP
Displacement: 500 CI, 8.2L
Bore x Stroke: 4.200 x 4.500
Compression Ratio: 12:1
Fuel: 93 Octane
Block: LS2 / Ductile Iron Sleeves
Head: LSW ALL PRO Ported (West Coast)
Rockers: Jesel Shaft Rockers (1.8:1)
Crank: Custom Callies Forged
Rods: Custom Carrillo A Beam
Pistons: Custom Wiseco
Camshaft: 248/248 @ .050, 117LSA, 0.660" LIFT
Intake: 102mm ERL
Throttle Body: 102mm ERL Electronic
POWER: 700 HP
TORQUE: 650 FT-LBS
This has bad *** heads, 12.1 compression, 102mm T/B, and so on. It's not MAX effort but is pretty damn healthy. Numbers don't look that promising for a build of this magnitude.I am sure with a nice sheet metal intake and a good size camshaft it would pick up considerably. RPM would be the limiting factor I would think.

That cam is tame for that size motor. Kumar dyno'd 650/610 w/ported GM Ls7 heads and hydraulic roller on an ERL 500ci. I don't remember the size of the cam, but he said it idled like a baby.
