That being said, LSX is so proven, and just plain works. I've known several people who messed around with aluminum blocks in big power applications to finally give up and swap to LSX then zero issues. One guy alone on a twin turbo LS application went through 3 ERL setups before swapping to LSX, and now zero issues. Car was ~1450rwhp.

I saw it for the first time last year at PRI after several months of getting to know one of their employees. The block itself is basically an aluminum copy of the LSX, its well engineered. The problem for me was how cocky the guys at PRI from concept performance were. I had many questions that they were unable to answer at the time and they also constantly spouted off about how "tested" it truly was. The bottom line is that at this point the only thing it was really tested in was sand rails based on what they were telling me.
They went on and one trying to convince me that if it can live in a sand rail it can live in anything, this is where the conversation took a turn and the bullshit meter went red. If they truly thought that a 1500-2000lb rail loads that engine anything like a 3000+lb car making 2000hp they have lost their minds.
Needless to say I had a short discussion about "dealer" pricing with them after this and went on my merry way after they told me they wanted $3200 per block and like a 20 block commitment.
This time last year there was a "dealer" for them on the west coast that was selling these blocks for $3600, now all of a sudden they have increased in price like 25-30% and are still unproven in any car making big power or fast passes to the best of my knowledge.
Do I think its a contender and a solid block, hell yea, its well made. But is it proven enough to command a price like that? Not a chance, based on that alone I would buy the Dart aluminum block at this point if that's what I was in the market for.
Just my $.02

no signs of torsional twist, no funny wear marks in bearings, no broken blocks to date. Look for big numbers this spring as several cars will be using LSR blocks nmca lights out 9.
