The C5R block is essentially the same base block of aluminium as the LS1/LS2/LS6/LS7 - their are slight internal differences and metalurci chanes.. but essentially the same light weight part.
It should be known that the LSx assembly is lighter than the M3 6-cylinder setup.. 
nth posted the weights one day if I am not mistaken.

7.0L V8 engine (tuned) making ~700hp......100hp/L
4.3L V8 engine (standard) making ~500hp.....more than 100hp/L.

Um...no.
Thats 620 RWHP. With an 18% loss to the rear wheels thats closer to 750hp and the car only weights 3100 lbs. I don't think your 4.3 (in that car) would be up to the task at taking on the Z.
I understand that the 4.3 is untuned and I absolutely will recognize that european engine tech is way beyond that over here in the US. Much more power out of smaller NA engines. But I still like the raw sound of that 7.0 v8. And there is also a price difference for those high tech high reving engines from europe. Oh well, each to his own.
Wait a minute....what car with a 4.3 are you refering to? If it's not N/A it doesn't count in this argument.

I assume he is refering to the F430. And what the LSX engines have over those technologically advanced high revving engines is reliability and they're basically bulletproof.
Compare the amount of times and cost it takes to service a Ferrari, but to service something like an Ultima GTR would be nothing compared to a Ferrari and it has the performance that would be compared with an Enzo.

Not only that, but have to also consider the modifications that need to be made so that the engine doesn't blow. Forged internals, lower compression ratios, rebuilt clutch, and on an Audi you can bet these things aren't cheap mods.

Granted with the cast iron blocked E46, but i do believe the new E90 6's with magnesium alloy blocks are a lot lighter, shame that new M3 engines gunna be a V8 and all
Nevertheless, the LS series of engines is a VERY impressive peice of engineering, and not only with a nice light 'all up weight' due to the lack of cam-train on the top end, the centre of mass is nice and low too.
Also, i'd just like to distinguish that making a pushrod set up as good as these being discussed is NOT easy, and its a testiment to the years spent developing this set up that is pushing very impressive numbers and giving good reliability.
However, the majority of pushrod designs in the mass market belong in tractors

I was using RC's figure of 700bhp......
Yes I was referring to the F430, which of course is an N/A engine.
Don't worry just trying to stir some shit.

Well, this tuned Z06 as a PWR similar to a McLaren F1, so you have to give it props.
