BS - the LS7 was so "unsucessful" and a "failure" that Chevy used it from 2006-2013 in the C6 and also on the Z28. I had an LS7 that was run hard and never gave me a hint of problems, as have thousands of other ZO6 owners.My bad,
The problem I see with that is the 7 litres of displacement in is a small block causes the cylinder walls to become way too thin like they were in the C6 Z06 engine. Everything becomes extremely fragile and brittle with the block. It's basically a small block at its limits of safety.
That C6 Z06 427 engine was a failure, an unreliable motor by chevrolet from the factory because was plagued with issues from the block to the cylinder heads. Anyways, I don't wanna get into that and cause another argument here, lol... but I agree that saves space but in a small block they probably learned that their 427 cid was not a successful move. They should've stay around 6.6 L , 400 cubic inches for more reliability in that expecific scenario but failed miserably.
And your small block theory is crap too - I had a Vette with an LSX454 (uhh, small block in case you don't understand that and of greater displacement than an LS7 - 454 > 427 last I checked) that ran on E85 and put down 630-640 rwhp all motor without a hiccup - used a bit of oil but it was basically a hc race motor with a huge cam - no surprises there. More importantly that motor/block can handle 2000 hp. So, no, I don't buy your inherent weakness of big cube LS motors contention.
